Silica fume, also known as microsilica or silica dust, is a by-product of the reduction of high-purity quartz with coke in electric arc furnaces in the production of silicon and ferrosilicon alloys (ASTM C1240[1], EN 13263[2].)It’s used in concrete field widely.
Silica fume Usage:
- enhancing mechanical properties
- improving durability
- enhancing constructability
- Improving resistance to corrosion
