A. Brush the surface of the material to improve its weathering resistance. Impregnating or brushing porous materials such as clay bricks, cement concrete, silicate concrete, and stone with water glass with a density of 1.35g/cm3 can improve the density and strength of the material. , impermeability, frost resistance and water resistance.
B. Reinforcing the soil: Alternately inject water glass and calcium chloride solution into the soil, and the resulting silicic acid gel will be in a state of expansion due to absorbing water in the soil in a humid environment, and the soil will be consolidated.
C. Prepare quick-setting waterproofing agent.
D. Repairing cracks in brick walls After mixing water glass, granulated blast furnace slag powder, sand and sodium fluorosilicate in an appropriate proportion, they are directly pressed into the cracks in the brick walls, which can play a role in bonding and reinforcement.
E. Sodium silicate aqueous solution can be used as the outer surface of fire doors.
F. It can be used to make acid-resistant mortar, which is used for the lining of furnace cellars. physicochemical properties.
