Microsilica JH97 is a dry powder powder.
Microsilica JH97 is a pozzolanic material that consists primarily of fine silicon dioxide particles in a non-crystalline form.
Microsilica JH97 contains a minimum of 97% silicon dioxide (SiO2)
Microsilica JH97: We have three factories in Shanxi, Yunnan and Qinghai Province, China. Stable quality and reasonable price.
