TOPKEN successfully used in the high-speed railway RPC cover plate

          TOPKEN Silica Fume has been successfully used in  the high-speed railway RPC cover plate, and achieve good application effect :

         1. Control the concrete materials’ segregation and secrete water, reduce or avoid concrete appear honeycomb, pits and weak sandwich, cracking.

          2. Improve the compressive strength of concrete

          3. Improve the durability of concrete, improve the resistance of concrete permeability, frost resistance, abrasion resistance and corrosion resistance.

          4. Improve the resistance of concrete anticarbonization.For the reinforced concrete, mixed with silica fume can improve and reinforced the bonding strength between base and rebal, still can enhance the ability of corrosion resistant steel.
