Abrasion Resistance of Coarse Aggregate and Compressive Strength of Concrete In Camarines Norte

Concrete has been long used in the field of construction. Coarse aggregate is a major component of concrete, and its size can vary. Abrasion resistance is one of its properties, which depending on the source and size of the aggregate, can impact concrete strength. Throughout the use of concrete, only abrasion resistance of concrete is correlated to the strength of concrete. Thus, this study aims to create a mathematical relation between the abrasion resistance of coarse aggregates and the compressive strength of concrete, considering two nominal maximum sizes from different quarries in Camarines Norte. Experimental methods such as the Los Angeles Abrasion Test, Paired t-test Analysis, The One-Way Analysis of Variance, and Bivariate Correlation Analysis were employed to investigate the substantial correlation between the abrasion resistance of coarse aggregate and the compressive strength from three different quarries, with reference to ASTM and ACI standards governing concrete. The result shows that among the three quarries, only Calabasa attained the standard abrasion resistance of coarse aggregate of 50%. Hence, only in One-Way Analysis of Variance resulted a significant relationship but not in Paired t-test Analysis and Bivariate Correlation.
