A kind of accelerated cement base infiltration crystallization type selfreparing waterproof material and preparation method thereof

The invention discloses a kind of accelerated cement based penetrant crystalline selfreparing waterproof materials and preparation method thereof, the accelerated cement base infiltration crystallization type selfreparing waterproof material is made of following components in parts by weight: 55~75 parts of portland cement, 25~45 parts of quartz sand, 3~10 parts of buffer, 4~12 parts of active component A, active component B4~15 part, 2~6 parts of swelling agent, 1~12 part of calcium ion replenishers, 1~4 part of water-reducing agent.Waterproof material disclosed in this invention is made by simple physical mixing processes, presetting period is short, chloride ion content is low, it can penetrate into inside cement-based material and form crystalline solid blocking microcrack, its anti-folding and anti-pressing ability and secondary impermeability ability are improved, while also assigning cement-based material permanent self-healing properties and good waterproof, endurance quality.In addition, the accelerated cement base infiltration crystallization type selfreparing waterproof material preparation method is simple, to the of less demanding of equipment and technique, there is very strong application power.
