Supplementary Cementing Materials - The Portland Cement ...

Slag cement is hydraulic and can be added to cement as an SCM. Silica fume, also called condensed silica fume or microsilica, is a finely divided residue resulting from the production of elemental silicon or ferro-silicon alloys that is carried from the furnace by the exhaust gases. Silica fume, with or without fly ash or slag, is often used to ...

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.
