This premium-grade bondbreaker contains organic compounds that react with the excess lime in concrete. They can also be divided into water-based or non-water based products. 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. Already a member? WebBond breaker tape shall be an adhesive-backed glazed butyl or polyethylene tape which will adhere to the premolded joint material or concrete surface. Always apply to a test area first to determine actual coverage rate before full-scale application. Out-of-plane shear loads can be transferred by providing a shear key, as shown in Figures 3a, 3d, 3e, 3f, 3h and 3i. Because there is no lateral support at the bottom of the lintel, provision must also be made for load transfer between the panels. In addition, care should be taken to provide joints at locations of stress concentrations such as (see Figure 1a for unreinforced masonry and Figure 1b for reinforced masonry): Consideration must also be given to the effect of control joint placement on load distribution within the wall. The backer rod provides a uniform foundation for the sealant.

Figure 3h is a variation on this approach, where one horizontal bond beam reinforcing bar extends across the control joint, and is similarly debonded to allow longitudinal movement. When a bond breaker is needed at a FY 2017-18 GRAVITY WALL DESIGN STANDARDS However, if the opening is completely surrounded by reinforcement as shown in Figure 2c and 2d, the area around the opening is strengthened and control joints can be placed away from the opening. 0000005657 00000 n %%EOF WebSilcoseal Advantage is a water-based bondbreaker and tilt-up cure for use on tilt-up, lift slab and precast construction projects. Bond breakers are Potential cracking resulting from externally applied design loads due to wind, soil pressure, seismic forces, or differential settlement of foundations is controlled by structural design considerations not addressed here. The joint should be no deeper than its width, preferably depth is 1/2 the joint width. Sure-Lock Bracket The engineered method is generally used only when unusual conditions are encountered such as dark-colored units in climates with large temperature changes. 0000002187 00000 n ft./gal, Coverage will vary due to various amounts of different fillers, extenders, or additives in the concrete mix that can result in the concrete mass and finished surface having a higher than normal porosity and some very porous hotspots. Coverage ratios must be adjusted to compensate for resulting penetration and additional coverage coats required to provide proper surface treatment.
