Evaluation of the elastic modulus of concrete based on indentation test and multi-scale homogenization method

This paper aims to quantitatively evaluate the elastic modulus of concrete through microscopic tests and a multi-scale mechanical homogenization method considering interface transition zone (ITZ). The mechanical properties tests were carried out for concrete samples with 0% or 10% silica fume. The elastic modulus and volume fraction of individual phases of hardened paste and elastic modulus and thickness of the ITZ around coarse aggregate were...
