3.06 PRESTRESSING
A. Circumferential Prestressing Equipment:

1. The circumferential stressing system shall produce a continuously, electronically (or substantial equivalent) monitored permanent stress or force recording along its full length as it is being applied and the stress variation in any strand at any point around the circumference shall not be greater than +/- 1.5 percent of the ultimate strength of the steel. In addition to this recording, any system which deflects the tensioned prestressing material between the tensioning device and the wall after it has left the tensioning device, shall provide a similar continuously monitored stress or force record along its full length as it is being applied to the wall. These recordings shall show that either before or after deflection that the stress variation in the prestressing material at any point around the circumference shall not be greater than +/- 1.5 percent of the ultimate strength of the steel.

2. Due to prior instances of force measurement inaccuracies and the inherent problems associated with hand-held stressometers, no manually recorded force readings will be accepted. This requirement shall be strictly followed.

3. Any wrapping that does not meet the stress tolerances specified and/or cannot meet the requirements of above will not be accepted and will be removed at the expense of the Tank Contractor. The Tank Contractor is responsible for all costs associated with meeting the specified tolerances.

4. Since intermittent force applications can result in an unequal stress distribution around the wall (due to friction losses), the prestressing system shall be capable of applying a continuous wrapped force at any point around the circumference within the specified tolerances. Circumferential stressing systems based on jack-operated cable or rod-type tendons (such as those placed inside of ducts incorporated in the corewall or placed manually around the exterior of the corewall) will not be allowed.

5. Since wrapping systems which utilize single solid prestressing material will not provide the desired bond between the prestressing material and the shotcrete and since single solid prestressing material will not provide an adequate safety factor against failure, only machine wrapping systems which utilize seven-wire prestressing strandwrapping will be allowed.

B. Circumferential Prestressing Application:

1. All cracks in the core wall and floor slab shall be repaired as specified following the circumferential prestressing of the tank walls.

2. Wrapped strand shall be anchored to the wall at least once for every coil or reel.

3. Permanently anchoring one strand to a previously wrapped strand will not be permitted. Wrapped strand ends shall be joined by suitable splicing methods that shall develop 90 percent of the full strength of the strand.

4. Use of different alloys in the splicing material shall not be permitted.

5. The clear vertical spacing between any two wrapped strands shall be

1.5 strand diameters or 3/8-inch, whichever is larger. A 1/4-inch construction tolerance shall apply to strand spacing, as well as to this minimum spacing requirement.

6. All wrapped strand not meeting the spacing requirements shall be spread by approved methods or shall otherwise be removed.

B. Placement and Testing of Shotcrete:

1. Shotcrete shall be applied by an ACI 506 certified nozzleman.

2. Manually applied shotcrete shall be applied with the nozzle held at a small upward angle not exceeding five degrees and constantly moving during application in a smooth motion with the nozzle pointing in a radial direction toward the center of the tank. The nozzle distance from the prestressing shall be such that shotcrete does not build up or cover the front face of the wire or strand until the spaces behind and between the prestressing elements are filled.

3. Unless applied by an automated shotcrete process, total cover coat thickness shall be controlled by shooting guide wires. Vertical wires shall be installed under tension and spaced no more than two feet apart to establish uniform and correct coating thickness. Monofilament line (100 lb. test) or 18 or 20 gauge high tensile strength steel wire shall be used. Guide wires shall be removed after placement of the cover coat.

4. Shotcrete applied by an automated shotcrete process shall be applied using the wet mix only. Nozzles shall be kept mounted on power driven machinery enabling the nozzle to travel parallel to the surface to be sprayed at a uniform linear or bi-directional speed. The nozzle shall be kept at a uniform constant distance from the surface, always maintaining a right angle spray of the material to the surface. The high velocity impact shall be developed pneumatically by injecting compressed air at the nozzle.

5. Testing:
a. Testing shall be by an independent testing laboratory, acceptable to Engineer, and engaged by and at the expense of the Tank Contractor. b. Test shotcrete in accordance with ACI 506, except as specified herein.

One test panel shall be made for each of the following operations: core wall, cove, wire cover, and cover coat. Test panels shall be made from the shotcrete as it is being placed, and shall, as nearly as possible, represent the material being applied. The method of making a test sample shall be as follows: A frame of wire fabric (one foot square, three inches in depth) shall be secured to a plywood panel and hung or placed in the location where shotcrete is being placed. This form shall be filled in layers simultaneously with the nearby application. After 24 hours, the fabric and

3. Sufficient time shall be allowed for each layer of shotcrete to set up so it may take the next layer without sagging.

4. The shotcrete shall be started at the bottom of the wall until all wrapped strand has been covered. Subsequent shotcrete layers may be applied from the top down or from the bottom up at the discretion of the Tank Contractor.

5. While the nozzle travels around the wall, the nozzle shall be raised or lowered at a uniform rate in such a manner that an adequate overlapping of coatings and a uniform finish will develop.

6. The nozzle shall be spiraled up or down around the tank to either the top or the bottom of the wall or to the termination of the intermediate strand layer.

7. To ensure proper penetration around the strand and proper conveyance of the material through the hose, a 5 to 7-inch slump of the mortar at the pump is recommended.

8. The application of the shotcrete in the number and thickness of layers specified herein is mandatory for proper penetration of shotcrete behind prestressing material and to reduce shrinkage due to more uniform in-depth drying of the shotcrete.

9. Each layer of wrapped prestressing steel shall be covered with shotcrete until a minimum clear cover of 3/8-inch or the diameter of the strand, whichever is greater, has been placed over the prestressing steel.

10. The final cover coat, to make up for the full thickness of shotcrete over the final strand layer, shall be applied in at least 3 layers of equal thickness.

11. Each layer of shotcrete shall be completed for the full circumference of the tank and substantially the full height of that layer before the next layer of shotcrete may be applied.

12. All shotcrete coatings shall be built up in layers of approximately 3/8-inch in thickness until the final required thickness has been obtained. The Tank Contractor shall demonstrate by a reliable means that the proper thickness of shotcrete has been obtained with each layer applied.

13. Unless otherwise specified on the Drawings, the minimum shotcrete cover over all wrapped steel shall not be less than the following:
