Evaluation of the mechanical properties of self compacting concrete using current estimating models
Estimating the modulus of elasticity, tensile strength, and modulus of rupture of self compacting concrete
Highlights ► We evaluate the applicability of current estimating models to SCC. ► The modulus of elasticity, tensile strength, and modulus of rupture were studied. ► A database of SCC mixtures and the measured mechanical properties was elaborated. ► Various statistical tools are used to compare the measured and estimated values. ► All models are suitable for use in SCC. The ACI models are generally more precise.
Abstract This study includes an analysis of the applicability of current models used for estimating the mechanical properties of conventional concrete to self-compacting concrete. The mechanical properties evaluated are: modulus of elasticity, tensile strength, and modulus of rupture. An extensive database which included the dosifications and the mechanical properties of 627 mixtures from 138 different references, was used. The models considered are: ACI, EC-2, NZS 3101:2006 (New Zealand code) and the CSA A23.3-04 (Canadian code). The precision in estimating the modulus of elasticity and tensile strength is acceptable for all models; however, all models are less precise in estimating the modulus of rupture.
