Bond breakers are anti-stick materials used on adjacent metallic or non-metallic substrates, such as concrete and steel. Thank you! Bond breakers are used in key components required for tilt-up construction. In simple language, one is called water-based, and the other is called non-water-based. In addition, it is applied to the concrete surface to reduce the cracking of the slab due to changes in atmospheric humidity. 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. When Why We Need to Use Bonding Agents The time of the application depends on the specification of the produce. This type of bond breaker does not form a membrane which can hold up the water. SNAP-CAP | Specification of Cinder Block | What Is a Concrete Block? 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. The provision to accommodate movement at predetermined locations with proper joint applications prevents the development of stresses that could rupture the concrete. SCP is a penetrating concrete treatment that does not change the surface of the concrete. Bond breaker systems can be optimized by installing foam backing rod in the junctions, on top of the cured membrane, before laying the screed. The Man Behind 9to5Civil.com. NOTE: The application of 1100 or VOCOMP series will interfere with the normal reaction of TILT-CRETE with the casting slab surface. Bond breakers can be used to improve joint performance. TDS.

Bond breakers allow the concrete to separate from each other without compromising the strength or appearance of the concrete. P10-2605. or call This installation featured our new AIR-SHIELD ALUMINUM SHEET MEMBRANE product. Bond breakers allow for differential movement between the precast concrete backer and the stone veneer, helping prevent staining and cracking of the veneer. Worldwide: 847.214.2100. TILT-CRETE is not recommended to be used with any other manufacturers bond-breakers. This cracks may take from as simple hair cracks, which with time, propagates, eventually leading to failure of the concrete member. If casting of concrete panels is delayed for more than 2 weeks after the final bond breaker application it will be necessary to check for a sufficient bond breaker film on the casting slab. PACKAGING It is used in precast units to remove precast from the formwork. A bond breaker is a separator substance applied in between adjoining solid surfaces to ensure that there is no adhesive molecular bond between the surfaces. 7.1 Introduction.

The reactive bond breaker will react with the concrete and produce crude soap. For both the curing and bond-breaking applications, once TILT-CRETE is sprayed on the surface, do not track over the slab until the surface is totally dry to touch. Basically, it consists of a pressure-sensitive adhesive on one side, and a bond-inhibiting material on the other side. This type of bond breaker will interact with the concrete surface and will create a waterproof film. Bond breaker concrete forms a sheet-like structure between two surfaces of concrete. What are the different types of handrails used in bridges? Definition: (1) adhesion of concrete or mortar to reinforcement or other surfaces against which it is placed, including friction and mechanical interlock; (2) adhesion of cement paste to aggregate; (3) adhesion, cohesion, or both between materials; (4) patterns formed by the exposed faces of masonry units, for example, running bond or Flemish providing a bond breaker. It is lightweight, highly flexible, and easy to cut or form in the field without waste. Over-application can result in delays due to drying, discoloration, panel surface dusting, surface irregularities, etc. DECK-O-JOINT is a decorative expansion joint for use wherever concrete is placed. Preformed Contraction Joint Because many backup materials act as bond breakers, a separate bond breaker material is not always required. It is economical, long lasting and trouble-free. Bond breakers are usually designed for curing compounds to slab and precast members. As shown in figure-2, a bond breaker tape in-between the joint sealant and joint filler is provided to facilitate free movement. 2.11 BOND BREAKER TAPE Bond breaker tape shall be an adhesive-backed glazed butyl or polyethylene tape which will adhere to the premolded joint material or concrete surface. standard lengths. Non-membrane forming bond breakers are divided into two types. In this scenario, TILT-CRETEs resistance to rain is highly reduced. Often a time, the importance of bond breaker as an inseparable part of the waterproofing system is being overlooked. Bond-breaker is applied to dowel bars to be placed in contraction joints in rigid pavement before placement of the concrete. 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. CERAMAR compresses easily for use with shrinkage-compensating concrete, and it may be used to relieve stress and pressure in concrete pavements.
