Silica fume for cementitious applications

Silica fume for cementitious applications

Blogs
Silica fume, also known as microsilica, is a byproduct of the silicon metal and ferrosilicon alloy production process. It consists of extremely fine spherical particles, which are around 100 times smaller than cement particles. Due to its unique physical and chemical properties, silica fume has become a valuable supplementary cementitious…
