Microsilica is a highly reactive pozzolanic powder produced during the manufacture of ferrosilicon and silicon metal alloys. Microsilica powder is composed of ultra fine solid spherical particles of amorphous silica each approximately 100 times smaller than a cement grain. It is formed by the condensation of vapour during the smelting of coal, quartz, iron ore and other materials in an electric arc furnace at around 2000.
