摘要：
Cementitious capillary crystalline waterproofing coating was developed, whose doping quantity of active substances was primarily determined by using orthogonal tests, the doping quantity of the active substances and the cement-sand ratio were optimized, and the formulation of the waterproofing coating was: 50.45% of silicate cement, 40% of quartz sand, 2.4% of assistants and 7.15% of active chemical substances. Test results showed that all the properties of the developed waterproofing coating conform to standard requirements, the bonding strength of wet substrate reached 1.8 MPa, and 28d seepage resistance reached 1.3 MPa.
