Embodiment Construction
[0029] In specific implementation, the raw material composition of cement-based permeable crystalline high-performance waterproof material according to parts by mass is listed in Table 1:
[0030] Table 1 Proportion of cement-based permeable crystalline high-performance waterproof materials
[0031]
[0032] The active masterbatch contains calcium carbonate and calcium chloride. The mass ratio of calcium carbonate and calcium chloride is 1:1. The total mass percentage of calcium carbonate and calcium chloride is not less than 97% of the active masterbatch for permeating crystallization. %; Cellulose is non-ionic cellulose hydroxypropyl methyl ether; rubber powder is a rubber powder copolymerized with vinyl tertiary carbonate and vinyl ester at a ratio of 1:2.27 by mass; water reducing agent is Powdered naphthalene water reducer, commonly used naphthalenesulfonate formaldehyde condensate; Portland cement particle size is 0.025-0.04mm; quartz sand particle size is 0.08-0.2mm; calcium...
