Differences between fly ash, slag and silica fume

Differences between fly ash, slag and silica fume

Supplementary Cementitious Materials (SCM) are added to concrete mixtures for various reasons including improving durability, decreasing permeability, aiding in pumpability and finishability, mitigating alkali reactivity and improving the overall hardened properties of concrete through hydraulic or pozzolanic activity or both. SCM are added to concrete in addition to or as a partial replacement of Portland

Microsilica

Advance Construction Material – Microsilica cement

Micro silica is an amorphous type of silica dust mostly collected in bag house filters as by-product of the silicon and ferro-silicon production. The paper summarizes important physical and chemical properties of micro silica and uses those results for an evaluation of micro silica from a Health Safety and Environment (HSE) standpoint. Micro silica consists
