Brief introduction of cement-based capillary crystalline waterproofing material (CCCW)
Keywords
CCCW, cement-based capillary crystalline waterproofing
Overview
Cement-based capillary crystalline waterproofing (CCCW) material is an inorganic waterproofing material which is mixed with Portland cement, active silicon and a certain amount of special active chemical substances. CCCW material has excellent waterproofness, impermeability and low cost. And green and pollution-free advantages.
Performance advantage
The current research on the application of CCCW materials is mainly on the optimization of concrete properties. The results show that it can significantly improve the mechanical properties of concrete and improve the internal structure of concrete.
Principle
The dissolved silicone ions in the CCCW cement-based permeable crystalline waterproof coating penetrate and diffuse in the concrete with the surface water, and chemically react with the calcium ions in the concrete to form water-insoluble calcium silicate hydrate (dendritic crystals), The crystals fill the capillary pores and combine with the concrete to form a whole, blocking the capillary channels inside the concrete, thereby making the concrete dense and preventing water leakage. In addition, CCCW has catalytic properties. Once it encounters water, it can continuously produce chemical reactions, and the generated crystals continue to grow and fill the capillary pores inside the concrete. Therefore, even if the concrete structure is partially damaged and leaks, it will crystallize after encountering water. The role of self-healing (0.4mm crack). CCCW has the characteristics and performance of multiple impermeability and self-healing, and has extremely strong compression resistance, up to 3.0MPa, the waterproof layer and the concrete surface form a complete system, which will not be separated, and the material can fully absorb the concrete surface The water can participate in its crystallization reaction, and the hollowing phenomenon will not occur. Due to its breathable and impermeable characteristics, it can be cured simultaneously with the concrete structure.
Composition
Cement-based permeable crystalline waterproof coating is a powdery rigid waterproof material made of special cement, quartz sand, etc. as the base material and infiltrated with a variety of active chemical substances. After interacting with water, the active chemical substances contained in the material penetrate into the concrete through the carrier water, form water-insoluble crystals in the concrete, block the capillary channels, and make the concrete dense and waterproof.
Product Features
