Ingredient Insight

Cement — Portland cement (OPC) is the primary binder in concrete. Hydration of its clinker minerals (C₃S, C₂S, C₃A, C₄AF) produces calcium silicate hydrate (C-S-H) gel, which gives concrete its strength. High early strength contribution but the most carbon-intensive ingredient — producing 1 tonne of cement releases ~0.6–0.9 tonnes of CO₂ from calcination and kiln fuel.
