Concrete is the most used construction material in the civil engineering. Concrete is the world’s most
consumable product next to water. The fly ash and GGBS has been used as partial replacement of cement in the concrete.
The fly ash is obtained as combustion of pulverized coal and collected by mechanical dust collector or electro static
precipitator. The GGBS is a 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 a 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 fly ash 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 fly ash and GGBS with various percentages. To study the fresh
properties slump tests, compaction factor tests and Vee-bee consistometer tests are conducted. To study hardened properties
compressive and splitting tensile strength tests are conducted and comparison study will be done.
