Example Embodiment

[0027] In the following, the present invention will be further described in conjunction with the embodiments:
[0028] The permeable crystalline concrete waterproofing agent of the present invention is made of the following components in parts by weight: 15-25 parts of sodium silicate, 3-6 parts of sodium methyl silicate, and 1-5 parts of sodium alginate. Parts, gelatin 4-8 parts, lauryl ethoxy sultaine 1-5 parts, sodium carbonate 1-3 parts, sodium citrate 1-4 parts, triethanolamine 1-4 parts, aluminum potassium sulfate 2 ~10 parts, calcium sulfate 2~6 parts, polyacrylamide 1~3 parts, calcium lignosulfonate 1~6 parts, carboxymethyl cellulose 3~6 parts, calcium hydroxide 2~5 parts, boric acid 1~ 3 parts, 60 to 90 parts of water. In specific implementation, spraying or brushing can be used to directly apply to the base surface that needs to be waterproofed, and repeated painting to a certain thickness, and curing for 3 days or more.
[0029] Table 1 shows the weight ratio of each component of 5 specific examples of the permeable crystalline concrete waterproofing agent.
