Cement GEL; The Cement Gel in a cement is a Calcium Silicate Hydrate ( CSH), which is responsible for the strength and binding in the structures. It is produced when a hydration reaction occurs by mixing water and cement; the paste is formed is called as cement gel.
When water is added to cement, the chemical reaction starts, which is known as the hydration process, and it is exothermic.
About 23% of water is required for a chemical reaction to take place, and 15% of water is required for gel formation. This formed cement gel is made up of calcium silicate and hydrate (c-s-H), which is important in strength property of cement paste.
So ultimately, the strength of cement gel is an important part of gaining strength and durability.
The cement gel in a cement is generally known as calcium silicate hydrate (CSH). It helps in strength and binding property. The production of cement gel occurs when a hydration reaction occurs by mixing water and cement; the paste so formed is called as cement gel.
