| 英文摘要: |
| A new type of cementitious capillary crystalline waterproofing material(CCCW) was prepared by using the four
factors and three levels orthogonal experimental method to optimize the components of capillary crystallization materials.
The waterproof effect of different age mortar matrix was studied，and the waterproof mechanism was analyzed. The results
showed that the crystal can permeate 20 mm depth through the coating，and the waterproof effect of matrix was
best when the CCCW material was coated on the surface of matrix on the third curing day. By coating the self-made waterproof
material，the impermeability pressure ratio of mortar specimen can be 400%，and it can be 333% when the material
was not coated. The crystal and precipitate can be generated when the hydration products of cement react with the
active substances of waterproof masterbatch，which can block the pores and improve the waterproof performance of mortar. |
