Fly ash dumped generally pollutes environment in the world. With the aim of sustainable development, the contribution of fly ash in concrete to the mechanical properties should be investigated. Variation of the modulus of elasticity of concrete is an important factor to evaluate the performance. In this study, the experiments were carried out over water-binder ratios of 0.34 and fly ash-binder ratios from 0% to 30%. The elasticity of modulus of high performance concrete replacing fly ash were determined on 7days and 28 days.
