Product Overview


Product Description


silica fume4Silica Fume, also called microsilica, is the by-product of the production of ferrosilicon or silicon(silicon metal) industrial. Silica Fume is an amorphous silicon dioxide(SiO2) generated as a gas in submerged electrical arc furnaces during the reduction of quartz. The whole process needs to be recycled with a dust-removing protection facility.Hot sale Silica fume (SiO2)

The individual of Silica fume particles are extremely small, approximately 1/100th the size of an average cement particle. Due to its fine particles, large surface area, and high SiO2 content, silica fume is a very reactive pozzolan used in concrete. The quality of silica fume is specified by ASTM C 1240 and AASHTOM 307.Hot sale Silica fume (SiO2)
