MARKCHEM MICRO SILCIA is composed of silicon dioxide (SiO2), collected from silicon metal and ferrosilicon. Micro Silica will react with the Calcium Hydroxide from the cement, which will form more of the Calcium Silicate hydrate, increasing the strength of the concrete. Using Micro Silica will also increase the durability of the concrete.

MARKCHEM Micro Silica is a high-performance pozzolanic material composed of amorphous silicon dioxide (SiO2) collected from silicon metal and ferrosilicon production. With typical purity levels of 85-98% SiO2 and ultra-fine particle size below 1 micron, it reacts with calcium hydroxide in cement to form calcium silicate hydrate (CSH), significantly enhancing concrete strength and durability. Widely used in high-strength concrete, refractory materials, and construction chemicals, this product is traded globally in bulk bags or drums for export to construction and industrial markets.
