Sodium silicate, commonly known as glass glue, is a colorless, transparent, viscous solid. Its aqueous solution, commonly known as water glass, is a mineral adhesive. Its chemical formula is Na₂O·nSiO₂, where Na₂O is an alkali metal oxide, and n is the molar ratio of silicon dioxide to the alkali metal oxide, called the molar number of water glass. The water glass commonly used in construction is an aqueous solution of sodium silicate.

Function
1. It is used as an activator for fly ash cement to improve the activity of fly ash, thereby improving the compressive strength and flexural strength of fly ash admixture cement; or increasing the amount of fly ash in cement, thereby increasing the Cement production and lower cement production costs. Powdered instant sodium silicate can also be used as quick-drying agent and reinforcing agent for ordinary cement.
2. Used as drilling cuttings coagulation agent and shale anti-swelling agent for silicon-based drilling fluids, bentonite slurry cemented leakage plugging agent and colloidal cement leakage plugging agent, precipitation chemical water plugging agent for oil and gas wells, and oil and gas well swelling agent Type water blocking agent.
3. It is used as a binder for unshaped refractory materials such as kiln gunning material, castable, acid-resistant cement, etc.; a mixture of foundry industry, ceramic industry, paint industry and thermal insulation material; thickener in oil production industry.
4. It is the main component of washing powder.
