Abstract

concrete is the most widely used construction material in civil engineering Industry because of its high
structural strength and stability. The concrete industry is constantly looking for supplementary cementations material
with the objective of reducing the solid waste disposal problem. Ground granulated blast furnace slag (GGBS) and
cow dung ash (CDA) are among the solid wastes. To overcome from this Crisis, partial replacement of cement by
GGBS and CDA can be an economic alternative. The experiments were designed to study the effect of adding GGBS
and in various percentages by weights 20%,30%&40% of cement and cure for the Periods of 3,7,14&28 days
respectively before testing for the compressive strength of concrete. In our project 56 cubes are casted for the
compressive strength of the concrete.
