Evaluation of modulus of elasticity of ultra-high performance concrete

Modulus of elasticity (MOE) is a significant parameter in the design of concrete structures. The use of local materials for developing ultra-high performance concrete (UHPC) is beneficial in saving energy and reducing the concrete cost. However, this practice possibly decreases the MOE of UHPC. This study synthesized all relevant experimental data in the literature to propose a new equation for predicting the MOE at different ages. A number of UHPC mixtures Were developed to verify the accuracy of the proposed equation. With an error of 10%, the proposed equation provides a reasonable prediction for the UHPC mixtures containing local materials. (C) 2017 Elsevier Ltd. All rights reserved.
