Performance Analysis of Locally Sourced Aggregates in Concrete Compressive Strength

Abstract

Different varieties of natural coarse aggregate are available in the Bangladeshi market, most of which are imported from various parts of the neighbouring nation, India. The purpose of this article is to identify the optimum mechanically strong locally accessible natural coarse aggregate for concrete preparation. It also focuses on the findings of an experiment inquiry into the impacts of three distinct types of natural coarse aggregate accessible in the Bangladeshi market, namely Bholaganj, Tamabil, and Panchagarh, on the mechanical characteristics of concrete. Each kind of natural coarse aggregate was used to make concrete cylinder specimens measuring 150mm X 150mm while the other materials remained constant. The study's concrete mix ratio and water/cement ratio were 1:1.5:3 and 0.52, respectively. At 7, 14, and 28 days of curing age, the compressive strength, splitting tensile strength, and modulus of elasticity were measured. The results revealed that Panchagarh is best suited for concreting, with significant differences in compressive strength, splitting tensile strength, and modulus of elasticity when compared to other types of natural coarse aggregates employed in the study.
