Foaming alkali is a water-soluble silicate, its aqueous solution commonly known as water glass, is a mineral binder. Its chemical formula is R2O. nSiO2, in which R2O is an alkali metal oxide, and N is the molar ratio of silica to alkali metal oxide, which is called the frictional number of sodium silicate. The common water glass used in building is the aqueous solution of sodium silicate. (Na2O. NSiO2)

Use of sodium silicate
A. To brush the surface of materials and improve their weathering resistance, the porous materials such as clay bricks, cement concrete, silicate concrete, stone, etc. can be impregnated or brushed with sodium silicate with a density of 1.35g/cm 3, which can improve the compactness, strength, impermeability, freezing resistance and water resistance of materials.
B and reinforced soil alternately pour water glass and calcium chloride solution into the soil. The silica gel generated in the wet environment solidifying the soil due to absorption of moisture in the soil.
C, prepare quick setting waterproofing agent.
D. Repairing brick wall cracks by mixing water glass, granulated blast furnace slag powder, sand and sodium fluosilicate in proper proportion and pressing directly into brick wall cracks can play a role of bonding and reinforcing.
E, sodium silicate solution can be used as the outer surface of the fire door.
F, can be used to make acid resistant mortar for lining of furnace cellar. Physicochemical properties
