ACC® microsilica products are tested in accordance with ASTM C 1240, EN13263:2005, and JIS A 6207 standards.
ACC is one of the earliest suppliers of micro silica in China. We provide micro silica with different grades and densities that is used in many famous construction projects in the world, applying in concrete, mortar, oil field cement, refractory, chemical fertilizer and other fields. ACC micro silica complies with ASTM C 1240 and EN13263:2005 standards, and has been recognized by SGS, Exova and other famous test authorities and ENR enterprises.
We select the best silicon products from top manufacturers. The recycle, densifying and filling processes are automatically integrated in a closed environment without any mixture or impurities.
Fix clients’ order in stable production bases so as to ensure the consistency and stability of quality.
We offer anti-UV & anti-aging plastic woven bag for long storage and also directly-used water soluble paper bag.
We own warehouses in both Tianjin and Xiamen, which ensures timely shipment for urgent needs from clients.
The products are passed through double quality check from both manufacturer side and ACC side before delivery.

With high pozzolanic activity index, high comprehensive strength and low LOI, ACC microsilica can be well-performed in construction application, which can improve the bond strength and abrasion resistance, reduce permeability, and protect reinforcing steel from corrosion.
ACC undensified microsilica can be well used in the refractory application. It can improve the fluidity of refractory casting materials, reduce water consumption, improve the compactness, temperature strength and thermal shock resistance.
ACC microsilica can also be well-performed in fertilizer, it can be used as moisture absorption, anti-caking agent, and pellet binding agent.etc.
