Determination of dynamic modulus of elasticity of concrete - Vol.93(11) Nov - Thane ACC LTD 2019 - 7-15p.
An experimental investigation was carried out to determine the dynamic modulus of elasticity of pozzolana Portland cement concrete. Large numbers of concrete cubes were prepared in the laboratory for investigation. The destructive and non-destructive tests were conducted on concrete cubes at different ages. The destructive test was conducted to obtain the compressive strength of concrete cubes. Ultrasonic pulse velocity of cubes was measured according to IS 13311 (Part 1). The recorded values are used to determine the dynamic modulus of elasticity of concretes. Based on experimentally obtained data and analysis, a few relationships are proposed to correlate the water/cement ratio, compressive strength, and elastic moduli of concretes. Several interesting findings are observed from the correlations of the coefficients while analyzed by regression analysis. This study helps to determine the static properties of concrete from the dynamic ones.
