Quantitative evaluation of elastic modulus of concrete with nanoidentation and homogenization method

This paper aims to evaluate the elastic modulus of concrete with nanoidentation technique and homogenization method. In this paper, concrete is divided into two parts: coarse pore and matrix. It is assumed that matrix is composed of five phases: stone aggregate, ITZ-1 (interfacial transition zone around stone aggregate), sand, ITZ-2 (interfacial transition zone around sand) and paste. Based on the Ca/Si ratio change in interface region, the...
