Shrinkage cracks in concrete masonry are not a structural concern. Flat Expansion Joint Foam, 6 rolls (300 Ft). How will the finished concrete product be used and what type of chemicals, including sealants, adhesives, and coatings, will be applied on top of the concrete surface after the concrete has been poured? REGAN Vest: Inside Denmark's secret nuclear bunker TILT-CRETE is low-VOC formulation that does not contain wax or hydro-carbon resins. Stud Rail Highly Bendable: Easily creates tight radius / complex joints. If it rains within 12 hours of application, TILT-CRETE will need to be reapplied. Can use cut 'sonotube ring' or better, polyurethane wrap, to provide a gap for installation, and remove it the first time it is lifted. <<2F6130032B3F7D4E822F4C36175224FC>]/Prev 134655/XRefStm 1837>> Login. Water-Based Concrete Bond Breaker. Bond breakers are normally Discover how this hybrid manufacturing process enables on-demand mold fabrication to quickly produce small batches of thermoplastic parts. For this joint, the out-of-plane load transfer mechanism is provided by filling the adjacent ends of two stretcher units with grout or mortar. I've not used isolation joint for this purpose before (needing to lift the slab). Price/Tube. Bond Breakers and Their Effective Use - Concrete Over-application can result in delays due to drying, discoloration, panel surface dusting, surface irregularities, etc. Thin Slab Ferrule Insert H. Hidden in northern Jutland's Rold Forest, some 400km north-west of Copenhagen, is the sprawling bunker complex of Koldrigsmuseet REGAN Vest (The Cold War Museum REGAN West). Triple Flared Coil Loop Strap Tie (12 tubes/case). Wall Plug For positive bond breaking, it is essential the casting slab be 100% sealed with TILT-CRETE. Visually and physically inspect the slab to witness the entire surface has a definite sheen. Any dull spots must be recoated. Questionable areas can also be tested by dropping water on the surface. If the water beads-up or forms a bubble and does not penetrate the concrete surface, it is sealed. Any areas accepting penetration of the water must be recoated until a positive seal is achieved. Control joints are typically required in exposed above grade concrete masonry walls, where net aesthetic shrinkage cracking may detract from the appearance of the wall, and to limit moisture or air infiltration. 0000008377 00000 n Remove and Replace or Top With Unbonded Overlay 0000060667 00000 n Standard Specification for Nonrigid Vinyl Chloride Polymer and Copolymer Molding and Extrusion Compounds, ASTM D2287-12. Wood Chamfer It is placed to ensure that there is no adhesive molecular bond between the surfaces. the bonding of subsequent concrete pours. Easy-Lift S contains a red fugitive dye to aid in the application process. Category: Bond Breakers May help contribute to LEED credits: #164 is a time-proven, hot-applied polymeric sealant which combines a tenacious adhesive power with high resiliency. 170 0 obj <>/Filter/FlateDecode/ID[<41CF01A5B51A6F41B60B4EFF94845807>]/Index[148 55]/Info 147 0 R/Length 113/Prev 298344/Root 149 0 R/Size 203/Type/XRef/W[1 3 1]>>stream When a bond breaker is needed at a endstream endobj startxref Additionally, since foundation walls are subjected to relatively constant temperature and moisture conditions, shrinkage cracking in below grade walls tends to be less significant than in above grade walls. Where external loads are an issue in combination with internal volume change, the design should consider the combined effects of these influences on cracking.

Always apply to a test area first to determine actual coverage rate before full-scale application. PACKAGING WebThe unique top tear strip is removed (during trowelling of fresh concrete) to quickly create an exact top joint shape for sealants. Place tear-off strip facing up if caulking is desired after concrete hardens. A bond breaker is a substance applied to concrete surfaces to guarantee that there is permanent bonding between the surfaces. the excess lime in concrete. I doubt actual "tar" paper is readily available. 0000007571 00000 n US/MC-SAE Threaded Splice Bar Meets the moisture retention requirements of ASTM C309 when applied to steel-troweled surface finish. In Figure 2a, continuous vertical reinforcement cannot be provided in the cell adjacent to the opening on the left, as crossing the horizontal portion of the control joint (i.e., the slip plane) would effectively pin the two sections together, restraining relative movement. STORAGE Bondbreaker B should be stored in a cool, dry place in original unopened containers. 0000017992 00000 n TILT-CRETE cures the concrete floor or casting slab and top sides of panels once poured. It is applied to the casting slab to function as a bond breaker between the casting slab and the tilt-up or lift-slab panel. The product should be used where appearance is a prime consideration in tilt-up and lift-slab construction. Shear transfer devices such as preformed gaskets or shear keys (such as those shown in Figures 3a, 3d, 3e, 3f, 3h and 3i) may not be necessary when using openings wrapped with reinforcement in wall segments designed to resist the lateral loads applied directly to them plus those transferred from the opening enclosure. When stored indoors in original, unopened containers at temperatures between 40 90 F, optimum performance and best use is obtained within one year of date of manufacture. Do not under apply or over apply TILT-CRETE. If less than the recommended amount is applied, the film may not be continuous or of sufficient thickness to inhibit inter-slab moisture penetration which may result in panels sticking to the casting slab.
