<br />03300 - 8/22 <br />2.07 MISCELLANEOUS MATERIALS: <br />A. Damp proofing agent shall be an asphalt emulsion conforming to ASTM D1227, Type <br />III, Class 1. <br />B. Evaporation retardant shall create a monomolecular film on the concrete. The <br />retardant shall have no effect on cement hydration and shall meet local VOC <br />requirements. Evaporation retardant shall not effect adhesion of curing compounds <br />or other treatments and shall not effect the color of the concrete. <br />C. Reinforcement shall be per SECTION 03200 Concrete Reinforcement. <br />D. Water Stops shall be per SECTION 03100 Concrete Formwork. <br />E. Damp proofing agent shall be a waterborne emulsified-asphalt. Damp proofing shall <br />be suitable for "green" or slightly damp surfaces and shall withstand normal <br />expansion and contraction of the concrete. Damp proofing agent shall breath to <br />allow vapors to escape. Damp proofing agent shall meet local VOC requirements. <br />F. Bonding agents shall be 100% solids, epoxy adhesives conforming to the following: <br />1. For bonding freshly-mixed, plastic concrete to hardened concrete, bonding <br />agent shall be a medium viscosity adhesive conforming to ASTM C 881 Ty pe <br />II, Grade 2, Class C, <br />2. For bonding hardened concrete or masonry to steel, bonding agent shall be a <br />non-sagging gel adhesive conforming to ASTM C 881 Type I or IV, Grade 3, <br />Class C. <br />G. Vapor Barrier: <br />1. Vapor Barrier shall consist of a composite of heavy kraft paper, asphalt, <br />fiberglass reinforcement, and polyethylene film. The composite shall be <br />laminated under heat and pressure. <br />2. Vapor Barrier shall comply with federal specification UU-B-790A, Type I, Grade <br />A, Style 4. Vapor Barrier shall have a water vapor permeance of less than 0.30 <br />perms when tested per ASTM E 96. <br />3. Vapor Barrier shall be installed under concrete slabs of all habitable spaces. <br />Barrier shall be installed per the manufacturer recommendations and per <br />ASTM E 1643. <br />H. Non-Waterstop Joint Material: <br />1. Preformed Joint Material: Preformed asphalt-impregnated fiber conforming to <br />ASTM D 1751. <br />2. Bond Breaker: All bond breakers shall be roofing felt or 15 mils minimum dry <br />film thickness of bituminous paint as indicated. <br />2.08 CONCRETE DESIGN REQUIREMENTS: <br />A. General: Concrete shall be composed of cement, admixtures, aggregates, and <br />water of the qualities indicated. The exact proportions in which these materials are <br />to be used for different parts of the WORK will be determined during the trial batch <br />process. In general, the mix shall be designed to produce a concrete capable of <br />being deposited so as to obtain maximum density and minimum shrinkage, and, <br />where deposited in forms, to have good consolidation properties and maximum <br />smoothness of surface. The aggregate gradations shall be formulated to provide <br />fresh concrete that will not promote rock pockets around reinforcing steel or
