Abstract
Cementitious capillary crystalline waterproof materials (CCCW for short) offer durability and excellent waterproofing properties, making them a popular option for building waterproofing. Some scholars have studied the proportioning of such materials. However, these studies lack the relationship between the impermeability pressure of mortar and the components, and the mechanism of action is somewhat debatable. Therefore, we adopted a two-step method in our experiments. Firstly, we screened out the components that significantly impact impermeability from a variety of active components by orthogonal test. We then optimized the design of the active group ratio using the simplex lattice method. Lastly, we conducted a performance test of the optimal ratio and explored the waterproofing mechanism of homemade CCCW.
