Densified Microsilica (Silica Fume)

ACC® construction used microsilica is a by-product of the manufacture of silicon metal or ferrosilicon alloys, with SiO2 content ranging from 85% to 97%, bulk density 500 – 700kg/m3. They are classified as Grade 85D, Grade 90D, Grade 92D, and Grade 95D. It’s collected, and packed from silicon metal or ferrosilicon factories directly, the automatic and integrated production process guarantees the consistent quality.
