ANALYSIS OF GGBS CONCRETE COLUMN

Abstract

The increasing search for an alternative sustainable and eco-friendly construction materials has led to research on various replacement materials in concrete that have properties similar to that of cement. Ground Granulated Blast Furnace Slag (GGBS) has inbuilt cementing properties which can be used as a partial replacement of cement in concrete. In this paper we have mainly focused on the analysis of M25 grade concrete by partial replacement of cement by GGBS. Cubes and Columns are tested for compressive strength after 7days and 28 days of curing. Water cement ratio for preparing concrete is 0.45. Percentage of cement replaced by GGBS are 25,50,75. It is found that normal M25 grade concrete fails to sustain the compressive strength as compared to the M25 grade concrete prepared by partial replacement of cement by GGBS.
