Concrete is the most used construction material in the civil engineering. Concrete is the world’s most consumable product next to water. The silica fume and GGBS has been used as partial replacement of cement in the concrete. The silica fume is obtained from electric arc furnace by burning the coal, coke, and wood-chips and collected by mechanical dust collector or electrostatic precipitator. The GGBS is by-product of iron and steel making industry, obtained by quenching of molten iron slag from a blast furnace in water or steam to produce a glassy granular product that is then dried and ground into a fine powder. By utilizing these two products as partial replacement of cement in concrete, the concrete can be made more eco-friendly by reducing the use of cement. In the present work, an attempt has been made to use a silica fume and GGBS as a partial replacement of cement. The main aim of this work is to study the fresh and hardened properties of M-30 grade control concrete and concrete made with partial replacement of silica fume and GGBS with various percentages. To study the fresh properties slump test, compaction factor test are conducted. To study hardened properties of concrete, compressive and split tensile strength tests are conducted and comparative study is carried out.

Silica Fume, Ground Granulated Blast Furnace Slag (GGBS), Compressive strength, Split tensile strength.
