The document is a report by the American Concrete lnstitute (ACl) thatdiscusses the causes, evaluation, and repair methods for cracks in concrete structures.

Causes and Control of Cracking in Concrete
This section outlines the various causes of cracks in concrete andmethods to control them. . Cracks can occur in both plastic and hardened concrete.o Plastic shrinkage cracking is caused by rapid moisture loss, leading to tensile stresses and shallow cracks.. Settlement cracking occurs due to local restraint during consolidation, influenced by bar size, slump, and cover. . Drying shrinkage in hardened concrete can lead to cracks due to moisture loss, with a shrinkage potential of up to 1%o. o Thermal stresses arise from temperature differentials, causing tensile stresses that can lead to cracking.
o Chemical reactions, such as alkali-silica reactions, can cause expansive reactions and cracking.
o Weathering processes, including freezing and thawing, can damage concrete and lead to cracking.
. Corrosion of reinforcement can cause Iocat radial cracks due to volume expansion from rust formation.
o Poor construction practices, such as adding excess water, can lead to increased cracking.
o Construction overloads can induce severe stresses, resulting in permanent cracks.

Evaluation of Cracking in Concrete
This section discusses the evaluation techniques for assessing cracks in concrete structures.
. Evaluation involves determining the tocation and extent of cracks.
. Proper selection of repair procedures is crucial based on the evaluation findings.
. Techniques for evaluation include visual inspection and measurement of crack width and depth.

Methods of Crack Repair in Concrete
This section details various methods available for repairing cracks in

Page 583 of 751 ends

V
concrete structures.
o Epoxy injection is a common method for repairing cracks.o Routing and sealing can be used to address surfice cracks.o Stitching and additional reinforcement can provide structural support.
o Drilling and plugging, gravity filling, and grouting are also effective repair techniques.
o Drypacking and crack arrest methods can be employed for specific types of cracks.
. Polymer impregnation and surface treatments can enhance durability and appearance.
o Autogenous healing is a natural process that can occur in some concrete mixes.

Summary and Acknowledgments
This section summarizes the report and acknowledges contributions. o The report provides guidance on the causes, evaluation, and repair of cracks in concrete.
o Acknowledgments are given to committee members and
contributors involved in the report,s preparation.
. The document serves as a resource for practitioners in the field of concrete construction.

Effects of Construction Loads on Concrete
ln cold climates, construction loads can unintentionally affect cast_in_ place concrete due to heating practices.
o Heaters should be positioned away from exterior concrete members to prevent high thermal gradients.
. High thermal gradients can lead to localized drying shrinkage and carbonation cracking.
o Construction activities can impose loads that exceed design limits, necessitating strict control to avoid overloads. . Designers must provide load limitations, and construction personnel must adhere to these guidelines.

Design and Detailing Errors in Concrete
lmproper design and detailing can lead to various issues in concrete structures, from aesthetic problems to catastrophic failures. o Common errors include poorly detailed reentrant corners, inadequate reinforcement, and lack of contraction joints.

Page 584 of 751 ends

ヽ _´
. High-stress concentrations near reentrant corners can initiate cracks, especially in window and door openings.o lnsufficient reinforcement in nonstructurat members can lead toexcessive cracking under load. o Properly designed walls should have contraction joints spaced 1 to 3 times the wall height to accommodate volume changes.

Externally Applied Loads and Cracking
Load-induced tensile stresses are a well-known cause of cracking in concrete members.
. Crack width increases with higher steel stress, cover thickness, and concrete area surrounding reinforcing bars.
o The most significant variable affecting crack width is steel stress.
o A simplified equation predicts maximum surface crack width in bending: w = 0.076 x (ratio) x (steel stress) x (cover thickness) x (area).
o ACI 318 limits crack widths to 0.016 in. for interior exposure and

0.013 in. for exterior exposure.

Evaluation of Cracking in Concrete
ldentifying the cause and extent of cracking is crucial before repairs are made.
. Cracks should be evaluated to determine if they indicate current or future structural problems.
o Observations, drawings, and construction records should be reviewed to assess the situation.
. Cracks that impair strength, stiffness, or durability require repair, especially in water-retaining structures.
o Monitoring crack movement and using nondestructive testing can provide insights into the condition of the concrete.

Selection of Repair procedures for Cracks
Repair methods should be chosen based on the evaluation of cracking causes and desired outcomes.
o Objectives of repairs may include restoring strength, improving watertightness, or enhancing appearance.
. Epoxy injection can restore tensile strength across cracks, but the underlying cause must be addressed.
. Routing and sealing is a simpler method for non-structural

Page 585 of 751 ends

｀中/
ー
repairs, while stitching can reestablish tensile strength.o Additional reinforcement may be necessary for significant cracks, and post-tensioning can close cracks effectively.

Methods of Grack Repair in Concrete
Various techniques exist for repairing cracks, each suited for specific conditions and types of cracks.
. Epoxy injection is effective for cracks as narrow as O.OO2 in. but requires careful execution.
. Routing and sealing involves enlarging cracks and filling them with sealant, suitable for flat surfaces.
o Stitching uses U-shaped metal units to span cracks, enhancing tensile strength.
o Chemical grouting can fill very fine cracks, while drypacking is used for dormant cracks with low water content.

Autogenous Healing in Concrete
Autogenous healing is a natural process that can repair cracks in moist environments.
o Healing occurs through continued cement hydration and carbonation of calcium hydroxide.
. Saturation of cracks with water is essential for effective healing. o Healing is ineffective if cracks are active or subjected to movement during the healing period.

Summary of Crack Evaluation and Repair
The report serves as a guide for evaluating and repairing cracks in concrete structures.
o lt emphasizes the importance of understanding the causes of cracking before selecting repair methods.
. Twelve repair techniques are presented, each with specific advantages and applications.
o The report highlights the need for carefut evaluation and selection of repair procedures based on desired outcomes.

Cracks in Concrete and Their Detection

PREFACE
Cracks in concrete have many causes. They may affect
appearance only, or they may indicate significant struc- tural distress or a lack of durability. Cracks may repre- sent the total extent of the damage, or they may point to problems of greater magnitude. Their significance de-
pends on the type of structure, as well as the nature of the cracking. For example, cracks that are acceptable for buildings may not be acceptable in water-retaining struc- tures.

The proper repair of cracks depends on knowing the
causes and selecting the repair procedures that take these causes into account; otherwise, the repair may only be
temporary. Successful long-term repair procedures must
attack the causes of the cracks as well as the cracks
themselves.

To aid the practitioner in pinpointing the best solution to a cracking problem, this report discusses the causes, evaluation procedures, and methods of repair of cracks
in concrete. Chapter 1 presents a summary of the causes of cracks and is designed to provide background for the evaluation of cracks. Chapter 2 d e s c r i b e s e v a l u a t i o n t e c h - niques and criteria. Chapter 3 describes the methods of crack repair and includes a discussion of a number of
techniques that are available. Many situations will require a combination of methods to fully correct the problem.

Preface to the 1991 Revision
Following the initial publication o f ACI 224.1R in
1985, the Committee processed two minor revisions. One
revision, published a s ACI 224.lR-89 s i m p l y u p d a t e d t h e format of recommended references. A second minor revi-
sion contained minor technical revisions and editorial
corrections in the document, and added a new section to Chapter 3, regarding the use of high-molecular-weight
methacrylates as sealer/healers.

During 1990 a Committee 224 Task Croup reviewed
the document and recommended the revisions contained
herein. Chapter 1 has been altered in only minor detail.

The introduction to Chapter 2 has been revised exten-
sively, and additional minor revisions have been made to the rest of the Chapter. In Chapter 3 , the section on
routing and sealing has been rewritten to include flexible sealing and overbanding of cracks, and it is updated to reflect current materials and construction practices. Sec- tion 3.2 on epoxy injection has been revised to be some- what more general and reflect current practice. The
for-
mer section on high-molecular-weight methacrylates has
been moved to Section 3.7 and retitled “Gravity Filling.” This recognizes the point that “high-molecular-weight
methacrylate” is a material, and not a method. Refer-
ences are presented in Chapter 5; citations throughout
the text have been revised to employ the author/date
format. Several new references have been added.

Additional revision of the report is ongoing. Commit-
tee 224 invites comment from the readers and users of
this report on new developments, or alternate viewpoints on the
Causes, Evaluation, and Repair of Crack s in Con-
crete Structures.

CHAPTER 1-CAUSES AND CONTROL

OF CRACKING

1.1-Introduction
This chapter presents a brief summary of the causes of
cracks and means for their control. Cracks are categor- ized as occurring either in plastic concrete or hardened concrete (Kelly 1981; Price 1982) . In addition to the in- formation provided here, further details are presented in ACI 2 2 4 R a n d a r t i c l e s by Carlson et al . (1979), K e l l y (1981), Price (1982),, and Abdun-Nur (1983). Additional references are cited throughout the chapter.

1.2-Cracking of plastic concrete

1.2.1 Plastic s h r i n k a g e cracking -"Plastic s h r i n k a g e cracking ( Fig. 1.1 ) occurs...when subjected to a very rapid loss of moisture caused by a combination of factors which include air and concrete temperatures, relative
humidity, and wind velocity at the surface of the con-
crete. These factors can combine to cause high rates of surface evaporation in either hot or cold weather.”
When moisture evaporates from the surface of freshly
placed concrete faster than it is replaced by bleed water, the surface concrete shrinks. Due to the restraint pro- vided by the concrete below the drying surface layer, ten- sile stresses develop in the weak, stiffening plastic con- crete, resulting in shallow cracks of varying depth which ----

may form a random, polygonal pattern, or may appear as
essentially parallel to one another. These cracks are often fairly wide at the surface. They range from a few inches to many feet in length and are spaced from a few inches to as much as 10 ft (3 m) apart. Plastic shrinkage cracks begin as shallow cracks but can become full-depth cracks.

Since plastic shrinkage cracking is due to a differential volume change in the plastic concrete, successful control measures require a reduction in the relative volume
change between the surface and other portions of the
concrete.

Steps can be taken to prevent a rapid moisture loss
due to hot weather and dry wind s (ACI 224R, ACI
302.1R, ACI 3 0 5 R ) . T h e s e m e a s u r e s i n c l u d e t h e u s e o f fog nozzles to saturate the air above the surface and the use of plastic sheeting to cover the surface between
finishing operations. Windbreaks to reduce the wind
velocity and sunshades to reduce the surface temperature are also helpful, and it is good practice to schedule flat work after the windbreaks have been erected.

1.2.2 Settlement cracking - After initial placement,
vibration, and finishing, concrete has a tendency to con- tinue to consolidate. During this period, the plastic con- crete may be locally restrained by reinforcing steel, a prior concrete placement, or formwork. This local re-
straint may result in voids and/or cracks adjacent to the restraining element ( Fig. 1.2). When associated with rein- forcing steel, settlement cracking increases with in-
creasing bar size, increasing slump, and decreasing cover (Dakhil et al. 1975). This is shown in Fig. 1.3 f o r a limited range of these variables. The degree of settlement cracking may be intensified by insufficient vibration or by the use of leaking or highly flexible forms.

Form design
(ACI 347R) and vibration (an d revibra-
tion), provision of a time interval between the placement of concrete in columns or deep beams and the placement
of concrete in slabs and beam s
(ACI 309.2R), the use of
the lowest possible s l u m p , a n d a n i n c r e a s e i n c o n c r e t e cover will reduce settlement cracking.

1.3-Cracking of hardened concrete

1.3.1 Drying shrinkage -A common cause of cracking
in concrete is restrained drying shrinkage. Drying
shrinking is caused by the loss of moisture from the
cement paste constituent, which can shrink by as much as 1 percent. Fortunately, aggregate provides internal re- straint that reduces the magnitude of this volume change to about 0.06 percent. On wetting, concrete tends to
expand.

These moisture-induced volume changes are a charac-
teristic of concrete. If the shrinkage of concrete could take place without restraint, the concrete would not
crack. It is the combination of shrinkage and restraint (usually provided by another part of the structure or by the subgrade) that causes tensile stresses to develop.

When the tensile strength of concrete is exceeded, it will crack. Cracks may propagate at much lower stresses than are required to cause crack initiation.

In massive concrete elements, tensile stresses are
caused by differential shrinkage between the surface and the interior concrete. The larger shrinkage at the surface causes cracks to develop that may, with time, penetrate deeper into the concrete.

The magnitude of the tensile stresses induced by vol-
ume change is influenced by a combination of factors, in- cluding the amount of shrinkage, the degree of restraint, the modulus of elasticity, and the amount of creep. The amount of drying shrinkage is influenced mainly by the
amount and type of aggregate and the water content of
the mix. The greater the amount of aggregate, the
smaller the amount of shrinkag e (Pickett 1 9 5 6 ) . T h e higher the stiffness of the aggregate, the more effective it is in reducing the shrinkage of the concre te (i.e., the shrinkage of concrete containing sandstone. aggregate
may be more than twice that of concrete with granite,

2 2 4.1 R-4 A C I C O M MI T T E E R E P O R T
basalt, or limestone (Carlson 1 9 3 8 ) ) . T h e h i g h e r t h e water content, the greater the amount of drying shrink- age (U.S. Bureau of Reclamation 1975).

Surface crazing (alligator pattern) on walls and slabs
is an example of drying shrinkage on a small scale.

Crazing usually occurs when the surface layer of the
concrete has a higher water content than the interior
concrete. The result is a series of shallow, closely spaced, fine cracks.

Drying shrinkage can be reduced by increasing the
amount of aggregate and reducing the water content. A
procedure that will help reduce settlement cracking, as well as drying shrinkage in walls, is reducing the water content of the concrete as the wall is placed from the
bottom to the top. Using this procedure, bleed water
from the lower portions of the wall will tend to equalize the water content within the wall. To be successful, this procedure needs careful control of the concrete and pro- per consolidation.

Shrinkage cracking can be controlled by using contrac-
tion joints and steel detailing. Shrinkage cracking may also be reduced by using shrinkage-compensating cement.

The reduction or elimination of subslab restraint can also be effective in reducing shrinkage cracking i n slabs-on- grade (Wimsatt et al. 1987). In cases where crack control is particularly important, the minimum requirements of
ACI 318 are not always adequate. These points are dis- cussed in greater detai l iu ACI 224R, which describes additional construction practices designed to help control the drying shrinkage cracking that does occur, and in
ACI 224.3R, w h i c h d e s c r i b e s t h e u s e a n d f u n c t i o n o f joints in concrete construction.

1.3.2 Thermal stresses-Temperature differences within
a concrete structure may be caused by portions of the
structure losing heat of hydration at different rates or by the weather conditions cooling or heating one portion of the structure to a different degree or at a different rate than another portion of the structure. These temperature differences result in differential volume changes. When the tensile stresses due to the differential volume changes exceed the tensile stress capacity, concrete will crack. The effects of temperature differentials due to different rates of heat dissipation of the heat of hydratio n of cement are normally associated with mass concrete (which can in-
clude large columns, piers, beams, and footings, as well as dams), while temperature differentials due to changes in the ambient temperature can affect any structure.

Cracking in mass concrete can result from a greater
temperature on the interior than on the exterior. The
temperature gradient may be caused by either the center of the concrete heating up more than the outside due to the liberation of heat during cement hydratio n or more rapid cooling of the exterior relative to the interior. Both cases result in tensile stresses on the exterior and, if the tensile strength is exceeded, cracking will occur. The ten- sile s t r e s s e s a r e p r o p o r t i o n a l t o t h e t e m p e r a t u r e d i f f e r - ential, the coefficient of thermal expansion, the effective modulus of elasticity (which is reduced by creep), and the degree of restraint (Dusinberre 1945; Houghton 1972,
1976). The more massive the structure, the greater the
potential for temperature differential and restraint.

Procedures to help reduce thermally-induced cracking
include reducing the maximum internal temperature, de-
laying the onset of cooling, controlling the rate at which the concrete cools, and increasing the tensile strength of the concrete. These and other methods used to reduce
cracking in massive concrete are presented in ACI
207.1R, ACI 207.2R, ACI 207.4R, and ACI 2 2 4 R .

Hardened concrete has a coefficient of thermal expan-
sion that may range from 4 to 9 x
lOA F (7 to 11 x 10”
C), with a typical value of 5.5 x
lOA F (10 x
lOA C).

When one portion of a structure is subjected to a tem-
perature-induced volume change, the potential for ther- mally-induced cracking exists. Designers should give spe- cial consideration to structures in which some portions are exposed to temperature changes, while other portions of the structure are either partially or completely pro- tected. A drop in temperature may result in cracking in the exposed element, while increases in temperature may cause cracking in the protected portion of the structure.

Temperature gradients cause deflection and rotation in
structural members; if restrained, serious stresses can result (Priestly 1978; Hoffman et al. 1983; ACI 343R).

Allowing for movement by using properly designed con-
traction joints and correct detailing will help alleviate these problems.

1.3.3 Chemical reaction-Deleterious chemical reac-
tions may cause cracking of concrete. These reactions
may be due to materials used to make the concrete or
materials that come into contact with the concrete after it has hardened.

Some general concepts for reducing adverse chemical
reactions are presented here, but only pretesting of the mixture or extended field experience will determine the effectiveness of a specific measure.

Concrete may crack with time as the result of slowly
developing expansive reactions between aggregate con-
taining active silica and alkalies derived from cement
hydration, admixtures, or external sources ( e.g., curing water, ground water, alkaline solutions stored or used in the finished structure.)
The alkali-silica reaction results in the formation of a swelling gel, which tends to draw water from other por- tions of the concrete. This causes local expansion and
accompanying tensile stresses, and may eventually result in the complete deterioration of the structure. Control measures include proper selection of aggregates, use of low alkali cement, and use o f pozzolans, w h i c h t h e m - selves contain very fine, h i g h l y a c t i v e s i l i c a s . T h e f i r s t measure may preclude the problem from occurring, while
the later two measures have the effect of decreasing the alkali to reactive silica ratio, resulting in the formation of a nonexpanding calcium alkali silicate.

Certain carbonate rocks participate in reactions with
alkalies which, in some instances, produce detrimental ex- pansion and cracking. These detrimental alkali-carbonate

CAUSES, EVALUATION AND REPAIR OF CRACKS 224.1R-5
reactions are usually associated with argillaceous
dolomitic limestones which have a very fin e grained
(cryptocrystalline) structure (ACI 201.2R). The affected concrete is characterized by a network pattern of cracks.

The reaction is distinguished from the alkali-silica
reaction by the general absence of silica gel surface
deposits at the crack. The problem may be minimized by
avoiding reactive aggregates, dilution with nonreactive aggregates, use of a smaller maximum size aggregate, and use of low-alkali cement (ACI 201.2R).

Sulfate-bearing waters are a special durability problem for concrete. When sulfate penetrates hydrated cement
paste, it comes in contact with hydrated calcium alumi- nate. Calcium sulfoaluminate is formed, with a subse-
quently large increase in volume, resulting in high local tensile stresses that lead to cracking which causes
development of closely spaced cracking and deteriora-
tion. ASTM C 1 5 0 T y p e s I I a n d V portland c e m e n t , which are low in tricalcium aluminate, will reduce the
severity of the problem. The blended cements specified
in ASTM C 595 are also useful in this regard. In severe cases, some pozzolans, known to impart additional resis- tance to sulfate attack, could be used after adequate
testing.

Detrimental conditions may also occur from the appli-
cation of deicing salts to the surface of hardened con- crete. Concrete subjected to water soluble salts should be amply air entrained, have adequate cover of the rein-
forcing steel, and be made of high-quality, low per-
meability concrete.

The effects of these and other problems relating to the durability of concrete are discussed in greater detail in ACI 201.2R.

The calcium hydroxide in hydrated cement paste will
combine with carbon dioxide in the air to form calcium
carbonate. Since calcium carbonate has a smaller volume than the calcium hydroxide, shrinkage will occur (com-
monly known as carbonation shrinkage). This situation
may resul t
in significant s u r f a c e c r a z i n g a n d m a y b e especially serious on freshly placed surfaces during the first 24 hours when improperly vented combustion
heaters are used to keep concrete warm during the
winter months.

With the exception of surface carbonation, very little
can be done to protect or repair concrete that has been subjected to the types of chemical attack described above (ACI 201.2R).

1.3.4 Weathering-The weathering processes that can
cause cracking include freezing and thawing, wetting and drying, and heating and cooling. Cracking of concrete
due to natural weathering is usually conspicuous, and it may give the impression that the concrete is on the verge of disintegration, even though the deterioration may not have progressed much below the surface.

Damage from freezing and thawing is the most com-
mon weather-related physical deterioration. Concrete
may be damaged by freezing of water in the paste, in the aggregate, or in both (Powers 1975).

Damage in hardened cement paste from freezing is
caused by the movement of water to freezing sites and by hydraulic pressure generated by the growth of ice crystals (Powers 1975).

Aggregate particles are surrounded by cement paste
which prevents the rapid escape of water. When the ag-
gregate particles are above a critical degree of saturation, the expansion of the absorbed water during freezing may crack the surrounding cement paste or damage the aggre- gate itself (Callan 1952; Snowdon and Edwards 1962).

Concrete is best protected against freezing and
thawing through the use of the lowest practica l water- cement ratio and total water content, durable aggregate, and adequate air entrainment. Adequate curing prior to
exposure to freezing conditions is also important. Allow- ing the structure to dry after curing will enhance its
freezing and thawing durability.

Other weathering processes that may cause cracking in
concrete are alternate wetting and drying, and heating
and cooling. Both processes produce volume changes that may cause cracking. If the volume changes are excessive, cracks may occur, as discussed in Sections 1.3.1 and 1.3.2.

1.3.5 Corrosion of reinforcement-Corrosion of a metal
is an electrochemical process that requires an oxidizing agent, moisture, and electron flow within the metal; a
series of chemical reactions takes place on and adjacent to the surface of the met al (ACI 201.2R).

The key to protecting metal from corrosion is to stop
or reverse the chemical reactions. This may be done by
cutting off the supplies of oxygen or moisture or by sup- plying excess electrons at the anodes to prevent the
formation of the metal ions (cathodic protection).

Reinforcing steel usually does not corrode in concrete
because a tightly adhering protective oxide coating forms in the highly alkaline environment. This is known as
passive protection.

Reinforcing steel may corrode, however, if the alka-
linity of the concrete is reduced through carbonation or if the passivity of this steel is destroyed by aggressive ions (usually chlorides). Corrosion of the steel produces iron oxides and hydroxides, which have a volume much great-
er than the volume of the original metallic iron (Verbeck 1975). This increase in volume causes high radial bursting stresses around reinforcing bars and results in local radial cracks. These splitting cracks can propagate along the
bar, resulting in the formation of longitudinal cracks (i.e., parallel to the bar) or spalling of the concrete. A broad crack may also form at a plane of bars parallel to a con- crete surface, resulting in delamination, a well-known
problem in bridge decks.

Cracks provide easy access for oxygen, moisture, and
chlorides, and thus, minor splitting cracks can create a condition in which corrosion and cracking ar e acceler- ated.

Cracks transverse to reinforcement usually do not
cause continuing corrosion of the reinforcement if the
concrete has low permeability. This is due to the fact that the exposed portion of a ba.r at a crack acts as an anode.
