Evaluation of concrete creep properties based on indentation test and multiscale homogenization method

This paper aims to quantitatively evaluate the creep properties of concrete through microscopic tests with a multiscale mechanical homogenization method considering interface transition zone (ITZ). The concrete samples with 0 or 10% silica fume were subjected to a 360-day macroscopic test. A series of indentation tests, microscopic tests and theoretical studies were carried out to obtain the creep properties of individual phases of hardened...
