Anti-cracking concrete waterproofing agent

Abstract

An anti-cracking concrete waterproofing agent is prepared from raw materials in parts by weight as follows: 15-20 parts of zeolite powder, 5-10 parts of an AF-2 efficient water reducer, 6-8 parts of butyl stearate, 4-9 parts of polymethyl triethoxy silane, 2-6 parts of sodium cumenesulfonate, 1-5 parts of cryolite powder, 7-11 parts of rosin soap, 3-8 parts of zinc borate, 6-9 parts of dimethyl siloxane, 2-5 parts of 4-tert-butylphenol, 4-11 parts of sodium carboxymethylcellulose, 2-6 parts of gelatin powder, 7-9 parts of cellulose grafted chitosan and 3-8 parts of silicon carbide. The anti-cracking concrete waterproofing agent has the benefits of good water reduction and crack resistance effects, low cost and capability of improving mortar property.

Description

technical field [0001] The invention relates to an anti-crack concrete waterproofing agent. Background technique [0002] After ordinary concrete is hardened under general curing conditions, there will always be a certain degree of water seepage or leakage. It is very important to improve the waterproof and impermeable performance of concrete. It has the function of improving the impermeability and waterproof of concrete, and the impermeability grade can reach above P25. At the same time, it has the functions of retarding, early strength, water reduction, and crack resistance, and can improve the workability of fresh mortar: it can replace lime paste. It is especially suitable for concrete for bungalow roofs, large-volume waterproof concrete, hydraulic concrete, waterproof mortar, etc. Existing waterproofing agents have shortcomings in varying degrees, and people are working hard to improve the performance of concrete waterproofing agents.
