Abstract

The cement base permeating and crystallizing waterproof material consists of cement 50-65 wt%, active material 5.5-14.5 wt%, methyl cellulose as densifier 3.5-8.0 wt%, anhydrous citric acid as retarder 2.0-4.5 wt% and ground quartzite 20-40 wt%. It is used for anti-seepage and waterproof treatment of concrete structure through spreading the dry powder to the surface of newly deposited concrete structure or painting the mixture with water to the upstream face or downstream face of concrete structure. It has excellent permeating and crystallizing, anti-seepage and waterproof performance.

Description

technical field [0001] The invention relates to a concrete anti-seepage and waterproof material and its production process and construction method. Background technique [0002] In construction projects, ordinary concrete has poor impermeability and waterproof performance, and cracks often occur. In order to achieve the purpose of concrete impermeability and waterproof, methods such as adding waterproof admixture, adding more cement or increasing sand rate are often used in impermeable concrete. To be on the safe side, coiled materials, coatings and other materials should be used for double waterproofing on the facing or back surface of the impermeable concrete, which greatly increases the construction cost and prolongs the construction period. Because the waterproof interface must be flat and dry when laying the coiled material, the waterproof construction process is also relatively complicated, the overall cost is high, and the maintenance cost is also high. In addition,...
