Sodium Silicate - an overview | ScienceDirect Topics

Sodium Metasilicate. Sodium silicate has been successfully used as a chemical grouting material for many years. It is used in particular during the drilling of very permeable formations (Xiang 2007). When an aqueous mixture of sodium silicate and an activating agent, such as an ester, is injected into the ground, the silicate solution reacts to form a colloid, which polymerizes further to form a gel.
