A Practical Equation for Elastic Modulus of Concrete

The mechanical properties of concrete are highly dependent on the types and proportions of binders and aggregates. Because existing equations for predicting the modulus of elasticity as a function of compressive strength are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression, the existing equations cannot cover the entire experimental data. In this study, more than 3000 data sets obtained by many investigators using various materials have been collected and analyzed statistically in order to develop a reliable new equation for elastic modulus of concrete. The compressive strengths of the considered concretes range from 40 to 160 MPa (5.8 to 23.2 ksi). The new equation also takes into consideration the types of coarse aggregates and mineral admixtures. The proposed formula should be effective in the design of both normal strength concrete and high strength concrete structures.
