Experimental Studies on Strength and Durability Properties of Concrete with Partial Replacement of Bethamcherla Stone Aggregate

摘要

Concrete is an extraordinary and key structural material in the human history. Increase in construction activities has lead to an increase in demand for various raw materials in concrete. This lead to researchers to make use of alternate materials as ingredients of concrete those are in no way inferior to the conventional materials. By partially replacing the normal aggregate with Bethamcherla stone aggregates in different proportions, the strength of concrete can be determined. Based on the proportion of ingredients used in concrete, its properties can also be changed. In most of the building works normal conventional concrete is used. The present experimental work focused on effective use of bethamcherla waste materials in place of coarse aggregate in concrete mix since these materials are naturally and abundantly available in Kurnool district. Concrete grade of M20 is exercised with various replacement levels of coarse aggregate with 20mm bethamcherla stone aggregates like 0%, 25%, 50%, 75%, 100% to study the compressive strength and acid resistance of cubes with addition of steel fibers.
