Slag Cement: Performance and Sustainability Benefits

Slag cement improves the properties of concrete in its plastic and hardened states. When properly proportioned in concrete mixtures, slag cement is particularly suitable for enhancing workability, increasing 28-day strengths, lowering permeability to chlorides, providing resistance to sulfate attack and alkali-silica reactivity (ASR), and producing a lighter, more pleasing color.
