ASTM C1240 Silica Fume in Cementitious Mixtures

American ASTM C1240 Silica fume Industry standard:

SiO2: ≥85.0%
H2O: ≤3%
Igloss: ≤6.0%
Grain size (45um sieves): ≤10%

We, Superior Abrasives Co., Ltd, have been exporting silica fume for more fifteen years. We have become the largest silica fume producer of stable quality and lower price in China, with clients from Australia, North America, middle east and south east Asia. The annual export volume is over 100,000MT.microsilica factory

Currently we offer four grades of silica fume (micro silica) :
Densified and Undensified, SIO2:>85%, 92%, 94% and >96%.

10kg / 20kg soluble paper bags x 84 on the pallets.
500kg / 950kg / 1000kg plastic woven bags x 2 on the pallets(with or without bottom output )
We can also produce according to your requirement.

We are pleased to send you free samples, if you are interested in that. If you have any need or any requirement, please contact us by E-mail
