Anti-cracking enhanced polyfiber silicon self-healing waterproof material
Product Introduction
This is a concrete waterproof product independently developed by our company. This product is an internal concrete admixture made of nano-active self-healing masterbatch and high-strength alkali-resistant fiber. It has the functions of impermeability, crack resistance and self-healing of cracks. After adding concrete, this product can effectively improve the tensile strength of concrete structure and reduce the problem of concrete cracking caused by shrinkage, settlement and other reasons. At the same time, the nanoscale active masterbatch of this product can be activated in the case of concrete cracking and leakage, and react again with water to generate crystals to fill and seal the cracking, achieving the effect of self-healing of cracks. This product can also reduce the hydration reaction rate of cement, delay the hydration heat release of concrete, and reduce temperature cracks.
Implementation Standards
GB 18445-2012 Type A
