Microsilica JH90 is a dry powder available in two forms,densified silica fume and undensified silica fume.
Microsilica JH90 is a pozzolanic material that consists primarily of fine silicon dioxide particles in a non-crystalline form.
Microsilica JH90 meets the requirements of ASTM C-1240 and contains minimum of 90% silicon dioxide (SiO2)
Microsilica JH90: We have three factories in Shanxi, Yunnan and Qinghai Province, China. Stable quality and reasonable price.
