Micro Silica, also known as Silica Fume or Condensed Silica Fume, is a highly reactive pozzolanic material composed of amorphous silicon dioxide (SiO2) with particle sizes 100 times finer than cement. Primarily used as a high-performance concrete additive and cement admixture, it enhances compressive strength, abrasion resistance, and chemical durability. Widely exported in bulk or big bag packaging for infrastructure, construction, and refractory applications in global markets.
