Because no mechanical interlock is provided between the two panels separated by this joint, out-of-plane loads are not transferred across this joint. The reactive bond breaker will react, forming a crude soap. Steel Ply These types of bond breakers are made of crude resins to form the thin film. For best performance, the vertical reinforcement should be placed in the cell immediately adjacent to the opening. ]$Ez'3BxyrHCs pHuNmX}\eB47Ar3x!ILCnT_3Ix+N!C{*{?y%Pzn$.(9(}] Ijcj2R\"r#GVw |agNAcXL Wing Nut (Coil Thread CAUTION: TO AVOID FOAMING, DO NOT MIX EXCESSIVELY. When design necessitates the construction of a control joint that provides a rated fire resistance and out-of-plane load transfer, the control joints shown in Figures 3d and 3e can be used. WebBond-Breaker Strips: Asphalt-saturated, organic roofing felt complying with ASTM D 226, Type I (No. Prior to any full-scale application of a subsequent paint, coating, sealer, adhesives sealant, grout, etc., W.

When a slip plane under the bond beam is used for openings larger than 6 ft (1.83 m), control joints are recommended on both sides of the opening as shown in Figure 2b. TILT-CRETE is used as a cure and bond-breaker in tilt-up, lift-slab, and precast concrete construction. Care should be taken when constructing this type of control joint to ensure that excessive mortar is not placed in the head joint of the two control joint units, whichcan potentially lead to bonding of the two panels. Price/Bag. If, after application of the bond-breaking coat, steel, or concrete-placing operations are delayed longer than two weeks, the bond-breaking coat should be inspected carefully to determine if it still provides 100% coverage. If rain strikes the surface before the coating is dry, any damaged areas must be recoated. After the TILT-CRETE film is dry, normal rain should not affect the surface. To resist the lateral movement around the slip plane, 24-in. See TEK 19-6A, Joint Sealants for Concrete Masonry Walls (ref. <<2F6130032B3F7D4E822F4C36175224FC>]/Prev 134655/XRefStm 1837>> Wedge (for use with Recess Member) Cast the slab separately from the piles, then set it on the piles.

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. Approval may be granted for the application of 1100 concrete cure or one of the VOCOMP series cure-and-seal products from W. R. MEADOWS to be used as a cure coat prior to the application of TILT-CRETE as a bond-breaker.

This information is generally available from the manufacturers of preformed gaskets. Meets the moisture retention requirements of ASTM C309 when applied to steel-troweled surface finish. Tampers Because there is no lateral support at the bottom of the lintel, provision must also be made for load transfer between the panels. If a curing or curing-and-sealing compound other than 1100 or VOCOMP series products are used, they must be removed prior to the application of TILT-CRETE.

Standard Classification System for Rubber Products in Automotive Applications, ASTM D2000-18. However, structural reinforcement, such as bond beam reinforcement at floor and roof levels that resists diaphragm cord tension, must be continuous through the control joint (see Figure 3g).

For an opening of up to 6 ft (1.83 m) in width that are not wrapped with reinforcement, a control joint should be placed at one side of the opening as shown in Figure 2a. At other points of wall stress concentration, control joints are used to effectively divide a wall into a series of isolated panels.

If utilizing concrete masonry veneered steel beams over openings in lieu of concrete masonry or precast lintels, it is critical that the steel beam not be welded to the bearing plate(s) where designated control joints are to be constructed, as this will pin the two sections together, restraining movement. 6 Rolls/Bag (300 feet). 0000053803 00000 n Don't rely on synthetic liquid bond breaker. Be sure to coat down the side of the pier past the expected depth of concrete cap. Stiffback Bracket The depth of sealant should be approximately the joint width to reduce sealant strain, and hence extend sealant life. strongback Tie Be sure that the top of the expansion joint foam is set at the top of the intended concrete pour. Stainless Steel Snap Tie It's purpose is to control the amount of caulking that goes into the joint, but more importantly, to "break" the 3 point "bonding" that occurs in the back of the joint and thus prevents the caulking from tearing open at this location. Resists wash off from normal rain and dew once dried. water impermeable barrier. The tape shall be the same width as the joint.
