Abstract

On the basis of experimental studies correlations were found between attrition rate of fine aggregates on one hand and consistency of fresh concrete and compressive strength of hardened concretes on the other. For fine aggregates complying with standard requirements, differences of up to 15 MPa (2100 psi) in compressive strength were observed between concretes made with high and low quality fine aggregates when other factors are essentially identical. For identical concrete mix proportions slump values between 190 and 0 mm (7.6 and 0 in.) were observed.
