Embodiment 1

[0029] A cement-based permeable crystalline waterproof material described in Example 1 of the present invention is composed of silicate cement, quartz sand, silica micropowder, water-repellent agent and cellulose.

[0030] The aforementioned ordinary Portland cement is 42.5R ordinary Portland cement; the particle size of the quartz sand is 100-200 mesh; the silicon micropowder is 800-1200 mesh; Said cellulose adopts methyl cellulose ether. According to the percentage by weight, it is specifically: 57% of 42.5R ordinary Portland cement, 37% of quartz sand, 5% of silica powder, 0.18% of water repellent, and 0.82% of methyl cellulose ether. The above components are evenly mixed.

[0031] Weigh each component according to the weight ratio, add ordinary Portland cement, quartz sand, silicon micropowder, water repellent, and cellulose into the mixing tank, fully stir and mix evenly, and stir for 25 minutes to 35 minutes.

Embodiment 2

[0033] A cement-based permeable crystalline waterproof material described in Example 2 of the present invention is composed of silicate cement, quartz sand, silica micropowder, water-repellent agent and cellulose. The aforementioned ordinary Portland cement is 42.5R ordinary Portland cement; the particle size of the quartz sand is 100-200 mesh; the silicon micropowder is 800-1200 mesh; Said cellulose adopts methyl cellulose ether. According to the percentage by weight, it is specifically: 42.5R ordinary Portland cement 55%, quartz sand 38%, silica micropowder (%), water reducing agent 0.17%, methyl cellulose ether 1.83%, and the above components are mixed evenly.
