Silica fume admixture used in high performance concrete performance: can prevent concrete from the corrosive chloride and seawater improving the high resistivity of concrete improving the wear resistance of building, like flight runway, aircraft carrier deck, high speed way can improve strong chemical corrosion resistance b. Silica fume admixture used in high intensity concrete performance: improving the compressive strength of concrete to 140mpa improving the modulus of elasticity of concrete to 40000mpa can make the flexural strength of flight runway to 14mpa with 28days apply for projects and precast assault with high early strength c. Silica fume admixture used in shotcrete concrete performance: reducing the shotcrete rebound rate loss to 50% improving the construction efficiency, one sprayed layer thickness up to 12inch strength the resistivity and lower the permeability can retain compressive strength and flexural strength.
