Problems solved by technology

However, the existing waterproofing agents are mostly composed of organic matter or a combination of organic matter and inorganic matter. After the concrete is removed, the organic matter will still have a negative impact on the environment.

Abstract

The invention belongs to the technical field of building materials, and discloses a total water sample inorganic permeable crystallization waterproof agent and a preparation method thereof. The totalwater sample inorganic permeable crystallization waterproof agent is prepared from, by weight, 3-7 parts of sodium fluoride, 5-25 parts of sodium silicate, 13-25 parts of inorganic silica sol, 3-7 parts of sodium hydroxide and 38-67 parts of water. The preparation method comprises the steps that 1, all ingredients are weighed in proportion, sodium silicate and sodium hydroxide are dissolved into water, the mixture is mixed to be uniform, and mixed liquid is obtained; 2, sodium fluoride is added into the mixed liquid, the mixture is mixed to be uniform, and second mixed liquid is obtained; 3, the inorganic silica sol is added in the second mixed liquid, the mixture is mixed to be uniform, and the total water sample inorganic permeable crystallization waterproof agent is obtained. The totalwater sample inorganic permeable crystallization waterproof agent has good impermeability and waterproof effects.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an all-water sample inorganic osmotic crystalline waterproofing agent and a preparation method thereof. Background technique [0002] Concrete is the most widely used building material in the world today. Due to the characteristics of the material itself and construction technology, concrete is a kind of non-uniform porous material, and its porosity can reach about 50% of its own volume at most. In particular, the macropores and capillary pores have the greatest influence on the structure and properties of concrete. Porous cement-based buildings are exposed to the natural environment for a long time and are vulnerable to air, water, and acid mist. Among them, the erosion of water on concrete, especially the penetration into the material through pores, will cause the corrosion of internal steel bars and accelerate the carbonization of concrete; water absor...
