Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm.

The main field of application is as pozzolanic material for high performance concrete. It is sometimes confused with fumed silica. However, the production process, particle characteristics and fields of What is Silica Fume?

Smaller proportions of silica fume were used because of the very high reactivity of silica fume with calcium hydroxide produced by the hydration of Portland cement . The influence of silica fume on the compressive strength performance for cementitious grouts containing 100% OPC; 95% OPC, 5% SF; and 90% OPC, 10% SF, is shown in Table 2.
