Concrete is a highly heterogeneous composite material on the microscopic length scale
(10− 6 m) to the mesoscopic length scale (10− 1 m). The heterogeneous structure of
concrete influences its macro mechanical properties. The multiscale approach is an effective
method to analyze the mechanical properties of composite material and support the design
of material. In this paper, a 3D multiscale model for prediction of tensile strength of concrete
is presented. The microstructure of Hydrated Cement Paste (HCP) is generated by the …
