Cementitious capillary crystalline waterproofing agent is a kind of powdery rigid waterproofing material mixed into concrete. When the concrete is mixed, it can form a complete body structure with the concrete, which makes the concrete bear high hydrostatic pressure, and can repair the crack of no more than 0.4 mm.
According to the standard of GB 18445-2012 Cementitious capillary crystalline waterproofing materials.
It can improve the compactness of cement concrete to the greatest extent. Through the catalytic crystallization of active substances, the defects such as filling up the pores in the cement concrete can improve the impermeability of the concrete to the maximum, so that the pouring and waterproofing can be completed in one time.
It has excellent self-healing function, and has auto-repair function for concrete micro-cracks. The auto-repair function is reactivated when water is available.
● It can improve the workability of concrete and increase the strength of concrete by 20-30% .
● The slump loss of fresh concrete can be reduced and the pumping property of concrete can be improved.
● Reduce the shrinkage and cracking of concrete itself.
● To prevent harmful chemical corrosive medium (such as chloride ion) corrosion, improve the durability of concrete.
It is suitable for permanent impermeability and waterproofing works of cement concrete of basement concrete structure, tunnel, sewage treatment pool, running water pool, sewer, elevator well, swimming pool, etc.
The admixture amount is 1%~2% of cement or cementitious material. The actual admixture amount will be determined according to the engineering practice.
