| Summary: | With more and more needs of entertainment and leisure for people leisure, the amount of swimming pool, water park and other facilities continue to grow. But In the long term, leakage has always been a major problem to affect the operation and maintenance of swimming pools. Therefore, there is an urgent need for a waterproof, corrosion, and repair function waterproof materials, it should have a good environmental adaptability and technology to improve this situation. Cement-based permeable crystalline waterproof coating is a kind of cement concrete waterproof material, which contains the chemical active substances as water a carrier to penetrate into the concrete. Cement hydration products produce water-insoluble needle-like crystals, it blocks the capillary holes and fine cracks. In this paper, the active master batch is added to the powder by the infiltration crystallization technology in the process of preparing the polymer cement waterproof coating. The effect of the active master batch on the self-healing time of the polymer cement waterproof coating is studied.
