Abstract null null 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 obtained by a series of microscop...

Abstract null null 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 paste and contact creep modulus and ...

Abstract In this paper, the hydration process and mechanical properties of UHPC matrix incorporated with limestone (LS) and different substitution rates of metakaolin (MK) were investigated. MK was added with five levels of substitution (0, 5%, 10%, 15% and 20%) and LS was kept at 30% of the total binder mass. Mechanical properties, hydration heat, hydration products and pore structure measurements were carried out for every mixture. The results show that the hydration rate as well as the hydrat...

Abstract 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 thicknesses of interfacial transition zone aro...
