Properties of cement compounds and Silica content in cement
The main raw material of cement is calcium carbonate and silica, and calcium silicate is formed after calcining. The main mineral composition of Portland cement is: tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. Silica (Si02) imparts strength to the cement due to the formation of dicalcium and tricalcium…
