Comparative Analysis of Young’s Modulus Predictions for Lightweight Aggregate Concrete

Abstract:

Many experimental and numerical works are attempting to predict the elastic properties of Lightweight Aggregate Concrete (LWAC). The purpose of this paper is to estimate the Young’s modulus of Lightweight Aggregate Concrete utilizing two-phase composite models. However, results of experimental data published in the literature were used as a platform, upon which, two-phase composite models had been utilized. The outcomes of this comparative analysis show that neither of the two-phase analytical models could be directly utilized for predicting Young’s modulus of LWAC. The Hashin-Hansen composite model provides a good prediction of experimental Young’s modulus of all LWAC tested with a maximum error percentage equal to 16.94%. This model provides an upper bound whereas the Counto2 model provides the lower bound of experimental Young’s modulus of LWAC.
