Cement-based waterproof paints are waterproof coatings permeating crystallized paints based on special cement, quartz sand, etc., and seep into powdered waterproof materials made of various active chemical substances. The silicate ion dissolved in waterproof coatings using the solid cement base spreads with surface water permeating in concrete and chemically reacts with calcium ion in concrete to produce insoluble calcium silicate in water hydraulics (cranch crystals) with crystals filled with porosity and integrated into concrete, clogged through the porosity lanes inside the concrete, thus condensing the concrete and preventing water leakage. In addition, cement-based water-proof coatings have catalytic properties, and once water encounters can produce a continuous chemical reaction, the crystals that are generated grow and fill the porosity of the concrete's interior, so that concrete structures, even if partially damaged, can produce crystallization and self-remediation (0. 4 mm crack). Cement-based waterproof coatings have multiple characteristics and properties that are resistant to seepage and self-rehabilitation, and are extremely resistant to pressure. They form a complete system of waterproofing and concrete surfaces, do not separate, and the materials can fully absorb the moisture of the concrete surface to participate in their crystallization and do not cause empty drums. Owing to its inhalant characteristics, conservation can be carried out in tandem with concrete structures. The use of cement-based water coatings is, of course, far from limited to the above-mentioned areas, such as grain depots,** pits, sewage treatment, dam maintenance, urban water pipeline repairs, etc. It is believed that, after several years, the breadth of its application will become more pronounced as the market prices of products stabilize. Cement-based waterproof paints are a green, green, waterproof coating that has been widely promoted, and in recent years the haze has become increasingly heavy, and environmental requirements have become more and more demanding, making the survival of enterprises more and more difficult, and environmentally sound waterproof products are needed by society. The green building commission of the united states of america, lead, is a universal green building assessment system, and infiltration of crystal-resistant products has been recognized as lead。
