Sodium silicate, also called water glass or Soluble Glass, is any one of several compounds containing sodium oxide, Na2O, and silica, Si2O, or a mixture of sodium silicates varying ratios of SiO2 to Na2O, solids contents, and viscosity. Traditionally, sodium silicates are classified according to the acid from which they are derived as Orthosilicate Na4SiO4; Metasilicate Na2SiO3; Disilicate Na2Si2O5; Tetrasilicate Na2Si4O9. They are also classified by an X-ray diffraction method according to their crystalline structure. All these compounds are colorless, transparent, glasslike substance available commercially as a powder or as a transparent, viscous solution in water. They can be dissolved in water to form a syrupy liquid. Some forms are slightly soluble, and some are almost insoluble; they are best dissolved by heating with water under pressure. The solutions are strongly alkaline. They are produced chiefly by fusing sand and sodium carbonate in various proportions. The use of sodium silicates is as a raw material for making silica gel. Also used in detergent; as a cement for glass, pottery, and stoneware; for fireproofing paper, wood, cement, and other substances; for fixing pigments in paintings and cloth printing.

Where is Sodium Silicate used in Construction?
 
1. Concrete Densification and Strengthening
 
Sodium silicate reacts with calcium hydroxide in concrete to form additional calcium silicate hydrate (C-S-H), improving:
  • Surface hardness
  • Abrasion resistance
  • Overall structural integrity
2. Waterproofing and Sealing
 
It is widely used as a waterproofing agent in:
  • Basements and foundations
  • Water tanks and reservoirs
  • Tunnels and underground structures
  • This helps prevent water ingress and enhances long-term durability.
 
3. Soil Stabilization
 
In infrastructure and groundwork projects, sodium silicate is used to:
  • Strengthen weak soil
  • Reduce permeability
  • Improve load-bearing capacity
 
4. Fire-Resistant Coatings
 
Due to its inorganic nature, sodium silicate is used in fireproofing formulations, improving safety standards in buildings.
 
5. Adhesives and Binding Applications
 
It acts as a binder in:
  • Cement-based products
  • Tile adhesives
  • Refractory materials

Dosage

 

Sodium Silicate is a compound mixture of sodium oxide i.e. Na2o with silica sand i.e. Sio2 with water. Sodium silicate is also called water glass. There are two process to manufacture liquid Sodium Silicate. 

To manufacture a lower ratio of Sodium Silicate by Hydrothermal process.

Mixture at Na2Co3 (Soda Ash) with Sio2(Silica sand) in furnace fuses  of more then 1100oC gives sodium silicate glass in lumps form which is  easily dissolved in hot water.We manufacture large range of sodium silicates, as per the customer's specific requirements.
