Silica fume for metro rpc cover plate

Silica fume for metro rpc cover plate it a silica fume that can be specifically added to rpc covers used in subways.Microsilica powder is a kind of neutral inorganic filler with very stable physical and chemical properties, does not contain crystalline water, does not participate in the curing reaction, and does not affect the reaction mechanism. silica fume for rail RPC particle size distribution is reasonable, dense, hard, wear-resistant performance, can greatly improve the tensile, compressive, impact strength and wear-resistant properties of the curing material, anti-abrasive capacity can be increased by 0.5-2.5 times. When the amount of 5-10%, the concrete compressive strength can be increased by 10-30%, flexural strength increased by more than 10%, impermeability increased by 5-8 times, carbonation resistance increased by more than 4 times, micro-silica powder concrete than ordinary concrete abrasion resistance increased by 0.5-2.5 times, cavitation resistance increased by 3-16…
