sodium carbonate in geopolymer
What is Sodium Silicate? InnovateUs
Sodium silicate is a versatile, inorganic chemical made by combining various ratios of sand and soda ash (sodium carbonate) at high temperature. This process yields a variety of products with unique chemistry that are used in many industrial and consumer applications.

Synthesis of advanced phosphatic geopolymers utilizing fly ...
In the present work, fly ashbased advanced phosphatic geopolymers were synthesized through a greener route by mechanochemical cogrinding of raw materials. This results in the formation of a solid precursor, which is converted into the advanced geopolymer by adding water alone, thus eliminating the hazards associated with alkali handling along with waste reduction.

A novel method to produce dry geopolymer cement powder
There are two reasons to utilize calcium carbonate in the production of dry activator. Firstly, sodium hydroxide reacts with calcium carbonate to produce calcium hydroxide and sodium carbonate and pirssonite Eqs. (1) and (2) and secondly, the remaining calcium carbonate from the reaction acts as a filler material which decreases porosity and increases the compressive strength of activated slag [29,30].
