Micro Silica Powder is an extremely fine powder that is gathered as a waste product from the manufacturing of silicon and ferrosilicon alloys. It is made up of spherical particles with a 150 nm average diameter. The primary field use is as a pozzolanic component in high-performance concrete. Our Micro Silica Powder is exceptionally pure and effective. As a result, compact concrete is hardened and has significantly increased strength and durability. This is safe to use.
