The reactive bond breaker will react with the concrete and produce crude soap. . This guide will help you choose the best concrete . SCP is a penetrating concrete treatment that does not change the surface of the concrete. Once the bond breaker is applied to the surface, then once the concrete is poured, the concrete will develop as its own separate property. Questionable areas can also be tested by dropping water on the surface. In addition, they enable the precast unit to lift and move after it has been created to the desired shape. It is ideal for both horizontal and vertical concrete projects. They are also used to resists shrinkage cracks, which may appear on the concrete during casting, due to the unexpected evaporation of water from the concrete surface. 5, 6, 12 Site Map For a unreinforced concrete pad it recommends dowel rods at joints with oil used as a bond breaker from the concrete. Bond breakers allow the concrete to separate from each other without compromising the strength or appearance of the concrete. When bond breakers are applied to the concrete surface, it eventually joins together with the old concrete surface and once the concrete is poured, they become inseparable.
