A kind of composite cement base osmotic crystalline waterproof material

The invention discloses a kind of composite cement base osmotic crystalline waterproof material, it is made up of the raw material of following weight：320 ~ 570 parts of portland cement；240 ~ 480 parts of quartz sand；60 ~ 250 parts of coarse whiting；5 ~ 150 parts of silicon ash；2 ~ 125 parts of redispersable latex powder；0.5 ~ 50 part of surfactant；0.5 ~ 30 part of catalyst；0.05 ~ 2 part of cellulose ether.After the present invention acts on water, active chemistry in waterproof material is due to stronger permeability, it can be deeply infiltrated into by carrier of water in the internal void of cement concrete, promote unhydrated cement granules that hydration reaction occurs, generate substantial amounts of acicular crystals, filling closing capillary channel, makes cement concrete have excellent water proof anti-seepage function；When producing new microscopic checks in concrete, when in humid conditions or having water infiltration, active chemistry will activate once again, new hydration reaction occurs for catalysis, new acicular crystals is generated in gap, filling blocks microscopic checks, has excellent self-repair function.
