1. Paint the surface of the material to improve its weathering resistance. Impregnate or paint porous materials such as clay bricks, cement concrete, silicate concrete, and stone with water glass with a density of 1.35g/cm³, which can improve the density of the material. , strength, impermeability, frost resistance and water resistance.
2. Reinforce soil. The water glass and calcium chloride solution are alternately injected into the soil, and the resulting silicic acid gel is in a state of expansion due to the absorption of water in the soil in a humid environment, and the soil is consolidated.
3. Prepare quick-setting waterproofing agent.
4. Repair cracks in brick walls After mixing water glass, granulated blast furnace slag powder, sand and sodium fluorosilicate in appropriate proportions, press them directly into cracks in brick walls, which can play a role in bonding and reinforcement.
5. Sodium silicate aqueous solution can be used as the outer surface of fire doors.
6. It can be used to make acid-resistant cement for the lining of furnaces. physicochemical properties.
7. Preparation of silica gel.

Properties of water glass
1. Strong adhesion: water glass solution, the higher the density, the stronger the adhesion. If urea is added to water glass, its bonding ability can be improved without changing the viscosity.
2. Strong corrosion resistance: water glass can resist the corrosion of various inorganic acids, organic acids and aggressive gases.
3. Water glass has a certain burn effect on the eyes and skin, and attention should be paid to safety during use.
