silica metal fume grade92

详情

Silica metal fume, also called as micro silica, silica dust, which is a by-product of producing silicon metal or ferrosilicon alloys.
Silica fume consists pimarily of amorphous (non-crystalline) silicon dioxide (SiO2). Because of its fine particles, large surface area,
and the high SiO2 content,
silica metal fume is a very reactive pozzolan when used in concrete. The quality of silica fume is specified by ASTM C ***0 and AASHTO M **7.
