Influence of crushed sand on the dynamic modulus of elasticity of sand concrete

This research work deals with study of the dynamic modulus of elasticity of sand concrete containing crushed sand. As the crushed sand was replaced by river sand in three different proportions which are 10%, 20% and 30% respectively. In this paper, the flexural strength, ultrasonic pulse velocity, and the dynamic modulus of elasticity will be examined. The results obtained showed that the sample consisting of 30%crushed sand +70% river sand, gave the best result for all the studied experiments.

Keywords:

sand concrete, flexural strength, ultrasonic pulse velocity, crushed sand dynamic modulus of elasticity,
