A bond breaker is a substance applied to concrete surfaces to guarantee that there is permanent bonding between the surfaces. T Anchor WebThe slab must be fractured all the way through and the bond between the concrete and any reinforcement must be destroyed, all without damage to the base profile or the base 8). The joint should be no deeper than its width, preferably depth is 1/2 the joint width. Cleanup To remove improperly or over-applied TILT-CRETE from panels, W. R. MEADOWS recommends using a commercially available, heavy-duty, concrete degreaser/stripper. panel and a strong, smooth, uniform and clean panel appearance.

WebA geotextile bond breaker is a nonwoven, needle punched fabric used between new concrete and an existing cementitious pavement layer. Steel Stakes Reminder: it is very important that nonstructural reinforcement, such as horizontal joint reinforcement which is typically used for crack control only, should not be continuous through a control joint, since this will restrict horizontal movement. An engineered method is presented in TEK 10-3 Control Joints for Concrete Masonry WallsAlternative EngineeredMethod, which is based on limiting crack width to 0.02 in. Trowels:- Hand- Power produce a water impermeable barrier on the surface of the casting slab.

Wedge Bolt Over-application can result in delays due to drying, discoloration, panel surface dusting, surface irregularities, etc. Meets the moisture retention 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. Common control joint details are illustrated in Figure 3. 2.12 PREFORMED CONTROL JOINT Trim-A-Slab is a product made from exterior-grade materials designed to replace rotten or missing wood tilt-up and precast construction. NOTE: The application of 1100 or VOCOMP series will interfere with the normal reaction of TILT-CRETE with the casting slab surface. When a bond breaker is needed at a construction joint, a curing compound, Mirafi MPBBC1450 bond breaker is a needle-punched nonwoven interlayer composed of polypropylene fibers, which are formed into a stable network such that the fibers retain their relative position for use as an interlayer for separating cementitious pavement layers.

Ties appearance. The number of bond-breaker coats and coverage rate needed to achieve a complete uniform film is dependent on the concrete mix design, placing and finishing procedures, environmental conditions, etc. However, some designers incorporate shear transfer devices to limit the relative movement between thetwo panels on either side of a control joint, thereby reducing the stress on the joint sealant and providing longer life.

Price/Bag. Excellent stability; does not require continuous mixing throughout the application; the material must be mixed only prior to application. The backer rod provides a uniform foundation for the sealant. In addition, walls with adequate horizontal reinforcement may not require control joints, as the reinforcement effectively reduces the width of shrinkage cracks. If TILT-CRETE application as a cure to the casting slab is delayed for several hours or until the following day, the surface should be moistened with water before application of TILT-CRETE.
