Mesoscale Modelling of Concrete: Need of Including Rheological Parameters

Abstract

Concrete is a highly complex and heterogeneous material which limits the characterization prediction reliability of the concrete by experimental investigations. To obtain a deeper knowledge about the behavior of the concrete, better understanding of mesoscale constituents of the concrete need to be analyzed. Interaction of different constituents and their parameters manipulating the microstructure is not strictly considered for computing macroscopic performance of the concrete. For realistic simulation of macroscopic performance of concrete, those disregarded parameters need to be examined and included for computational analysis, since mechanical behavior and characterization of concrete are highly influenced by mesoscopic structural arrangement of the concrete ingredients. Characterization of different components of the concrete is made by finite element meshing the individual component with desired approach to vitalize effective computational analysis. This paper reviews different mesoscale modelling approaches and recommends the need and inclusion of rheological parameters in mesoscale models
