E. If fresh concrete may check or crack prior to commencement of curing due to weather, materials used, or other reasons, keep concrete damp but not wet using indirect fine water spray until it is unlikely checking or cracking will occur, or until curing commences.

F. Concrete curing shall proceed as follows:

SURFACE DESCRIPTION
Unstripped
Forms
Method 1: Wet wood forms completely after concrete has been placed, and keep wet with water until forms are removed.

For steel forms, keep exposed concrete surfaces continuously wet until forms are removed.

If forms are removed within 14 days of placing concrete, continue curing as described for surfaces with forms removed
Construction
Joints between
Footings &
Walls
Method 2 (Moist Curing): Cover surface with at least 2 layers burlap or cotton mats.

Wet mats with water for duration of 14-day curing period until concrete in walls has been placed.

Horizontal non-architectural flatwork, including roadways, slabs, curbs, and walks may also be watercured by ponding or by covering with 2” of saturated sand in lieu of burlap or cotton mats.

Do not apply curing compound to joint surfaces.

Encasement
Concrete
Method 3: Cover surface with moist earth 4 to 24 hours after concrete is placed.

Earthwork operations that may damage concrete shall not begin until ≥7 days after concrete is placed.

Concrete
Surfaces not
Described
Elsewhere
Method 2 (Moist Curing) (described above)
Method 4 (Curing Compounds): As soon as concrete hardens enough to prevent marring on unformed surfaces, and within 2 hours after form removal, spray surface with 2 coats liquid curing compound at minimum 75-psi pressure and uniform coverage of ≤400ft2/gallon each coat.

Apply first coat as soon as finished concrete surface reaches uniformly damp appearance with no free water on surface.

Allow first coat to dry up to 4 hours, then apply 2nd coat perpendicular to 1st coat.

Respray concrete surfaces subjected to rainfall within 3 hours after curing compound application by method and at coverage specified.

Protect concrete surfaces to which curing compound is applied for duration of curing period from pedestrian and vehicular traffic or causes that will disrupt continuity of curing membrane.

Do not damage seal during curing.

If seal is damaged or broken, reapply curing compound over damaged portion.

Where curing compound is accidentally applied to surfaces against which concrete is to be subsequently placed, remove curing compound by wet sandblasting just before placing new concrete.

Where concrete is placed adjacent to panel coated with curing compound, apply curing compound to previously coated panel areas within 6’ of joint and apply to other locations where curing membrane is disturbed.

Following curing, remove visible traces of curing compound without damaging surface finish.

Appearance is a primary consideration for concrete surfaces exposed to view.

Apply curing compound evenly on these surfaces.

Repair variations in shade, color or tint, resulting from uneven application of curing compound.

Floor Slabs on
Grade
Method 5 (Curing Blankets): Before curing medium is applied, keep entire surface damp using nozzles that atomize flow so surface is not marred or washed.

Apply curing material using Method 4 (Curing Compounds) described above.

2-22-dp 03 39 00 – Concrete Curing - 5 of 6

SURFACE DESCRIPTION
After 1 hour but not more than 4 hours after applying curing material, wet surface with water delivered through fog nozzle.

Place concrete curing blankets on slab, with edges butted together and with joints between strips sealed with 2” wide strips of sealing tape or with edges lapped at least 3” and fastened with waterproof cement to form continuous watertight joint.

During first 3 days of curing, do not permit traffic or depositing of materials on curing blankets.

After 3 days, traffic or material deposits shall only occur on top of ⅝” minimum plywood sheets laid over curing blankets.

Leave curing blankets in place for ≥14 days.

Add water under curing blanket as necessary to maintain damp concrete surfaces.

Do not remove curing blankets until concrete for adjacent Work has been placed.

Should curing blankets tear or become damaged, replace damaged sections.

G. Dispose of excess curing water in manner that avoids damage to Work.

H. Hot-weather curing shall proceed as follows:

1. If surface moisture evaporation rate as determined by nomograph in ACI 305R, is expected to be >0.2 psf per hour such as to cause plastic shrinkage cracking, make provision for windbreaks, shading, fog spraying, or wet covering with light colored material in advance of placement.

2. Take such protective measures as quickly as finishing operations allow.

I. Allow concrete to cure ≥14 days before applying architectural finishes.

3.3 Field Quality Control
A. Refer to Section 03 30 00 for field testing and inspection of concrete.

B. Special inspection and field testing of Class AA and Class A concrete required by Chapter 17 of CBC (Table 1705.3) shall be completed by ICBO-certified special inspector selected by City and shall include:

1. Do not apply paint to contact surfaces before bolting, or welding.

G. Holes for shop bolts shall be sub-punched or sub-drilled at fabricator’s option ¼” less in diameter than that of finished holes, and reamed to size with parts assembled with the following exceptions:

1. Do not punch holes in material >⅞” thick.

2. At fabricator’s option, holes in material >⅞” thick may be sub-drilled to diameter specified for sub-punching or may be drilled full size with parts assembled, provided parts are adequately bolted or clamped together.

3. Holes in rolled beams and plate girders, including stiffeners and active fillers at bearing points may be sub-punched ⅛” less in diameter than that of finished holes, and reamed to size after assembly if material is not thicker than nominal diameter of bolt less ⅛”.

4. Holes in material ≤⅞” thick for bolts which do not transfer stress caused by external vertical loading may be punched full size or, at fabricator’s option, may be sub-punched ⅛” less in diameter than that of finished holes and reamed to size after assembly. a. This applies to holes for stitch bolts, lateral, longitudinal, or sway bracing and their connecting material, lacing, stay plates, diaphragms which do not transfer shear or stress, inactive fillers, and stiffeners at bearing points. b. However, holes through assembled material shall not pass through both reamed plies and plies punched full-size unless reamed holes have been sub-punched for fabricator’s convenience, or assembled material is >5 plies thick, of which main material consists of ≤3 plies.
