Study the mechanical and physical properties of sand concrete using crushed limestone sand

Abstract

This research work deals with the effect of using crushed sand resulting from quarry waste on the mechanical and physical properties of sandy concrete. As the crushed sand was replaced by river sand in three different proportions which are 40%, 50% and 60% respectively. In this study, the flexural strength, ultrasonic pulse velocity, and the dynamic modulus of elasticity will be examined. The results obtained showed a good improvement over all the experiments studied when adding crushed sand and thus it could be used as a substitute for river sand in sand concrete, as the ideal ratio for all test results upon replacement was 60% of crushed sand.
