  • Ordinary Portland Cement (OPC) primarily constitutes Tricalcium Silicate (C3S) and Dicalcium Silicate (C2S) making up 60–70 % and 20–30 % of the cement matrix respectively. During cement hydration, C3S starts to react faster contributing to early stage strength in comparison to C2S, which reacts slowly and is responsible for long term strength development of concrete. C2S is manufactured at lower temperatures compared to C3S, resulting in lesser emission of carbon dioxide as compared to C3S… CONTINUE READING
