EXPERIMENTAL STUDY ON STRENGTH CHARACTERISTICS OF CONCRETE BY REPLACEMENT OF CEMENT AND FINE AGGREGATE BY GGBS AND M SAND

Cement is the major component in making the concrete. Due to urbanization and industrialization, the production of concrete is increasing day by day. Based on researches, it is well known fact, that the production of cement emits carbon dioxide. A recent survey shows that for production of every ton of structural concrete, around 400 kg/m3 of carbon dioxide is liberated. So in present scenario it has become a matter of prime importance, to keep the cement production same and increase the production of substitute materials to the save the environment. Experiments are taking place for replacement of cement with mineral admixtures possessing same characteristics as that of the cement. Another scarce material is river sand which is due to the growing communities, as that of cement the replacement of river sand is also very important. Therefore in the present study M30 grade of concrete is considered to replace cement, by Ground Granulated Blast furnace Slag (GGBS) and natural sand by Manufactured Sand. The cement is replaced by GGBS as 10%, 20%, 30%, 40% and 50% with M – sand. Experiments are conducted to determine the compressive strength, flexural strength, split tensile strength and water absorption test.
