If a bond breaker is not applied before the installation of a waterproofing membrane system, there are high chances that the membrane will wear and tear, forming holes, which would allow moisture into the substrate below, rendering the whole purpose of waterproofing system pointless. ASPHALT EXPANSION JOINT can be used in 80% of all control joint applications. As the temperature drops, the concrete will contract. A bond breaker is applied to the surface of the formwork before pouring concrete into the precast concrete. During concrete construction, form oil, bond breaker, concrete splatter and other types of contaminants often contaminate reinforcement. splices. bond breaker material delivered. The product and aqueous emulsion reacts with calcium hydroxide (Ca (OH) 2 ) in the concrete and forms a gel which seals concrete surface pores, restricting moisture entry and exit. A grease-like feel to touch indicates over-application and can result in panel surface discoloration, dusting, surface irregularities, etc. However, as noted in the gure, through-wall ashings generally create a bond-breaker, which reduces the structural capacity of a masonry wall. Easy-Lift FD is applied to the concrete casting slab to efficiently prevent the bonding of subsequent concrete pours.

Concrete standards, materials, mixes and tests, placement, finishing, patching, grouting, and crack repair. The reactive bond breaker will react with the concrete and produce crude soap. KEYWAY Used in 80% of all control joint situations. 461.2 Materials Ensure that materials meet the requirements of the following Specifications: Material Section Silicone Sealant and Bond Breakers 833.2.06 Epoxy Resin Adhesives 886 For a list of silicone joint sealant sources, please see QPL 66 . DESCRIPTION Bond breakers allow the concrete to separate from each other without compromising the strength or appearance of the concrete. A bond breaker is defined in the NTCA Reference Manual as, "Any material preventing adhesion." Examples of these contaminants or impurities include dust, dirt, sealers, coatings, existing adhesives, residue from previous products installed, oil, wax grease, paint, curing compounds, loose particles, drywall dust and even standing water. Bond breaker tape is black polypropylene tape that provides an option to break the bond of the sealant between the joints between the surfaces of the concrete. The coefficient of thermal expansion in concrete is 0.0000055 per linear inch of concrete per degree Fahrenheit of temperature change, yielding approximately .66 inch of movement per 100 feet with a 100 F (38 C) temperature range.
