cement strength improve by cement grinding aid

Cement Strength and Cement Grinding Aid in Cement

How does the strength of cement come into being? Answer: after mixing cement and water, the clinker minerals are rapidly hydrated, forming a large amount of hydration products, hydrated calcium silicate (C - S - H) gel, and forming calcium hydroxide Ca (OH) 2 solution; hydration product hydrated calcium aluminate (C-A-H) react with calcium sulfate (CaSO4) in gypsum to produce ettringite (AFt ...
