Silica fume – Wikipedia
Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) 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 nm.

Properties of Silica Fume related to its applications
Silica fume has been recognized as a pozzolanic admixture that is effective in greatly enhancing mechanical properties. The addition of silica fume to concrete improves the latter’s durability by reducing permeability and refining pore structure, leading to a reduction in the diffusion of harmful ions and the calcium hydroxide content, resulting in greater resistance to sulfate attack.
