T401-2.3. Reinforcing Steel: Meet the requirements of Department Specification 415.

T401-2.4. Coarse Aggregate: Meet the requirements of Department Specification 901.

T401-3. Repair Methods

T401-3.1. General: Locate and inspect all the deteriorated areas indicated in the contract documents or designated for repair by the Engineer. Sound test the areas and the surrounding concrete surfaces to identify the size and locations of all cracks, spalls and delaminations in need of repair.

Mark or otherwise delineate the limits of proposed demolition on the concrete surface for review and approval by the Engineer. The proposed limits shall be verified, modified as necessary, and recorded by the Engineer. Do not perform concrete demolition/removal before approval and

TSP(T401); Page 4 of 6 recording of the approved removal limits.

T401-3.2. Demolition and Surface Preparation: Sawcut along the perimeter of the area to be restored. For horizontal or vertical spalls less than 1 inch deep, saw cut the perimeter of the repair area to neat lines such that a minimum thickness of repair mortar may be hand-applied in accordance with manufacturer’s recommendations. Feathered edges will not be allowed. For spalls greater than

1-inch deep, cut the upper perimeter of sound concrete to an angle sloping slightly upward to avoid entrapping air and water.

Remove deteriorated concrete to sound material within the sawcut limits (or to other limits as described in plans or as directed). Removal shall be performed by scarification or by chipping with light duty pneumatic or electric concrete chippers (30 lb. or less in general, 15 lb. or less adjacent to strand, reinforcing steel, and structural limits of construction). Remove concrete that is contaminated with grease or oil. Exercise caution during demolition to avoid damaging the existing reinforcing steel.

These repair areas shall be roughened to International Concrete Repair Institute Technical Guideline

No. 03732 CSP No. 7 or to guidelines provided by the manufacturer of the approved repair material.

Completely remove all cracked or unsound concrete. When Class 1 (0 to 1/64-inch) cracks are encountered, notify the Engineer for inspection. Concrete with Class 1 cracks but solid sounded may be left in place if so, directed by the Engineer.

Blast clean existing concrete surfaces that will be in contact with freshly placed repair material and clean to remove loose material and dust immediately before application of repair material.

T401-3.3. Reinforcement: Remove the concrete adjacent to the bar 1-inch depth to permit bond to the entire periphery of the exposed bar. If unsound concrete goes to a depth of two inches or more beyond the reinforcement, stop for direction from the Engineer. Prevent cutting or damaging of exposed reinforcing steel. Blast clean all reinforcing bars exposed after concrete removal in accordance with Society of Protective Coatings (SSPC) SP-10 “Near White Blast” to remove all bond-inhibiting materials and take necessary precautions to avoid damaging the surrounding area. Replace bars that have lost 25% or more of their original diameter over 1-foot in length, or as determined. When using new bars spliced in place, maintain the original cover, with the minimum lap required shall be 48 times the bar diameter and, if necessary, provide additional chipping. Dual bars providing equivalent or greater cross-sectional area may be used as approved.

Where the bond between existing concrete and reinforcing steel has been destroyed, or where the steel is exposed, remove the concrete adjacent to the bar to a depth that will permit modified concrete to bond to the entire periphery of the exposed bar. A clearance of 3/4 to 1-inch behind the bar is required for this purpose. Do not remove concrete more than 1 inch beyond the first mat of reinforcing steel encountered without approval. Prevent cutting, stretching, or damaging of exposed reinforcing steel.

Welded wire fabric shall be used on repairs with depths exceeding 2 inches. The welded wire fabric placed in repairs without exposed existing reinforcing shall have a minimum 1/2-inch depth adjacent to the wires to permit bond to the entire periphery of the wire. Place the welded wire fabric after the existing rebar has been cleaned. Tie the wire fabric at regular intervals, vertically and horizontally, not to exceed 8-inches, or as directed. Field bend the welded wire fabric to conform to any changes in the concrete surface profile.

T401-3.4. Mixing: Provide a Mix and Testing Plan for quantities in excess of 1.0 cubic foot at a single location for the Engineer’s written approval including: manufacturer’s specifications, TSP(T401); Page 5 of 6 method of mixing, means of application, and placement procedure to provide a homogenous pour free of cold joints. Use clean mixers and accurately proportioned ingredients. Mix the materials at the site in accordance with the specific equipment requirements. Ensure that the material, as discharged from the mixer, is uniform in composition and consistency.

T401-3.5. Placing, Curing and Finishing: Spalled or damaged areas of concrete shall be repaired using an approved material, applied, and cured in strict accordance with the manufacturer’s specifications. The Engineer shall approve the specific material and proposed method of placement to ensure that the application is appropriate. Match repair material surface to surrounding concrete surfaces. Provide “V”-groove construction joints, drip notches, or any other features required to match the existing. Forming may be required at larger areas. Temporary shoring may be required as temporary supports.

For formed repairs, form the area to be repaired to neat lines. Form must withstand the anticipated head pressure of the repair material and a minimum pressure of 10 psi. Apply form release agent, compatible to the repair material, to the interior surfaces of the form. Pump material into forms with proper venting to ensure complete filling of voids, starting with a port at the bottom of the form.

Perform external form vibration as necessary to insure proper consolidation. Cap vents when steady flow of material is ensured then fill until an immediate increase of 3 to 5 psi is detected. At the

Engineer’s discretion, gravity fed pours may be allowed in some cases for uniform deficiency shapes where quality control can be assured after trial installations.

Repairs shall be performed to ensure the approved repair mortar/concrete is carefully worked into the repair area to achieve complete contact between the repair mortar and the substrate concrete.

T401-3.6. Materials and Acceptance Testing: The testing of the pre-packed repair material shall conform with the sampling and testing for structural concrete design mixes as set forth in Standard

Specification 346-8. Lot sizes/sampling frequency consists as a minimum of one load of field batched material per day. The Engineer may increase the frequency of testing as needed based on test results of previous batches. Compressive testing will need to be conducted in accordance with ASTM C39.

Make 4 to 6 extra test cylinders (as requested) and test for compressive strength gain determinations.

The Engineer will determine the time of testing. Any material not meeting strength requirements, shall be removed, and replaced. Cure test cylinders in air for the full curing period required before testing.

Curing of repair material shall be in accordance with the manufacturer’s recommendations. Do not place repair material at ambient temperatures outside of acceptable temperature ranges provided by the manufacturer unless adequate protection is provided against adverse effects of extreme temperature conditions.

T401-4. Quality Control

Include the work under these Technical Special Provision in the Contractor Quality Control

General requirements set forth in Department Specification 105. The Quality Control Plan shall include as a minimum, the manufacturer’s technical recommendations, formulation for the repair material the means and methods and equipment for removing the deficient concrete and cleaning the reinforcing steel, repair materials, forming and placement methods.

T401-5. Method of Measurements
