CSA cements in concrete countertops: Rapid strength with a

Calcium trisilicate (C3S) is the compound responsible for early strength gain in portland cement. The other compound, calcium disilicate (C2S), forms more slowly and is responsible for longer term strength. C3S makes up about 50-60% of portland cement composition, while C2S makes up a smaller fraction of OPC, generally around 18-20%.
