PRODUCT OVERVIEW

DESCRIPTION

Silica fume, also known as microsilica, is a byproduct of silicon and ferrosilicon alloy production. It is a highly reactive pozzolan used as a supplementary cementitious material in concrete to enhance strength, durability, and resistance to chemical attack. Silica fume improves the workability and reduces the permeability of concrete, making it suitable for high-performance and sustainable construction projects. It also contributes to the reduction of CO2 emissions by replacing a portion of Portland cement in concrete mixtures. Additionally, silica fume is used in the production of advanced ceramics, refractories, and as a filler in various industrial applications.
