Concrete bond breakers are a type of chemical solution or substance that is used to break or prevent the bond between two types of concrete surfaces. The bond breakers work by creating a barrier between the surfaces, thus preventing any adhesion between the two when concrete is later applied. They can be used in areas such as bridge decks, parking garages, and interchanges where the use of rebars is common, and structures are built in segments.
Concrete bond breakers are usually applied to specific areas by spray, brush, or roller onto the surface before the pouring of fresh concrete. Depending on the formulation, manufacturers may provide specific instructions regarding the application method, coverage rates, and the thickness of the applied layer.
There are numerous benefits to using concrete bond breakers, such as:
Concrete bond breakers come in two different types, namely active and passive bond breakers:
While concrete bond breakers are useful in preventing concrete adhesion, care should be taken when handling them. It is important to ensure that the concrete is placed within a reasonable time scale after application of the bond breaker. This is to avoid the risk of the bond breaker being removed by wind, rain, or any external forces.
Appropriate personal protective equipment should also be used when handling concrete bond breakers. This may include gloves, protective clothing, and eye protection. The use of bonding agents should be avoided where properties are exposed to extreme temperatures or where the concrete will be subjected to significant movement.
Concrete bond breakers are important substances in civil engineering and construction. With proper application, use, and handling, they can provide numerous benefits, including cost savings, improved construction quality, and longer-lasting infrastructure. This comprehensive guide to understanding and usage of concrete bond breakers should be helpful for contractors, engineers, and anyone involved in concrete construction projects.
It was not a comprehensive as you may thought. There's nothing mentioned about the time frame of when to put the concrete Bond breaker on the fresh concrete. I think that's pretty important
