It is possible that under any circumstances, the execution of a concrete section may be abandoned in the middle of the work and the concreting will continue to complete the construction at another time after the final setting of the concrete. This will cause a reduction in concrete from resistance & permeability viewpoints because of no more suitable connection between new & old concrete. For this purpose, strength concrete adhesive is a suitable option which may not only connect the old concrete to new one but also is applicable in repairing jobs for better adhesion of repairing mortars to the old surfaces. In addition and upon composition with new concrete, it may cause more adhesion of particles and optimized the properties. Strength Concrete Adhesive is a polymer made from homo-polymer superficial resins which may have suitable reactions with water and concrete cement. Also it may increase the tension and bending resistance and durability of concrete. Of course the most important property of this product is increasing the adhesiveness and compression of concrete particles and further reduction of permeability as well.
