In construction, sodium silicate can be used for soil stabilization.

Sodium silicate typically appears transparent and offers excellent acid and heat resistance, along with high viscosity. However, it demonstrates poor alkali resistance and relatively low water resistance. These characteristics are essential to understand.

Moving from properties to applications—since understanding properties is crucial for proper usage—sodium silicate is primarily used as a key component in grouting agents during renovation. This application leverages its strong adhesive properties, ensuring the grout remains cohesive and delivers high effectiveness.

In construction, sodium silicate is also employed to reinforce soil, a common practice in building foundations. When mixed with calcium chloride solution, it expands and solidifies the soil upon reaction. This method is widely adopted and frequently observed.

Additionally, due to its exceptional heat resistance, sodium silicate is often applied as a coating on door surfaces. This thermal stability ranks among its most significant advantages, though this application is typically observed in furniture manufacturing facilities rather than everyday settings.

Finally, sodium silicate finds its most extensive use in the chemical industry, primarily as a raw material for producing other substances. Examples include silica gel, sodium metasilicate pentahydrate, and silica sol. While these applications are highly versatile, they are rarely encountered in daily life and are generally only visible within chemical production facilities.
