An experimental study of the application of Silica fume for the high strength concrete was conducted. Nine specimens with three different contents of silica fume, 0%, 10%, 20% and with three water-cement ratio 30%, 40%, 50% were tested. Results shows that 10% of silica fume and 30% of water-cement ratio has a maximum strength with 700kg/cm<sup>2</sup> of compressive strength and 64kg/cm<sup>2</sup> of splitting tensile strength and 100kg/cm<sup>2</sup> of flexural strength. Slump value of the tested samples decreases with increasing water-cement ratio and elapsed time of silica fume. Splitting tensile strength(□□)and flexural strength(□□)and static modulus of elasticity(E) can be correlated with compressive strength(□□)from a regression analysis.

An experimental study of the application of silica fume for the high strength concrete was conducted. Nine specimens with the variation of the contents of silica fume Owt%, 10wt%, 20wt% and that of water-cement ratio 30%, 40%, 50% were tested. Results show that 10% of silica fume and 30% of water-cement ratio has a maximum strength with 700kg/㎠ of compressive strength and 64kg/㎠ of splitting tensile strength and 100kg/㎠ of flexural strength. Slump value of the tested samples decreases with increasing water-cement ratio and elapsed time of silica fume. Splitting tensile strength(σ_t) and flexural strength(σ_f) and static modulus of elasticity (E) can be correlated with compressive strength(σ_c) from a regression analysis.
