Abstract:Basalt fiber reinforced concrete (BFRC) can be regarded as a composite of cement mortar, aggregate and
basalt fiber. In this paper, the influences of the basalt fiber’s length and content on the fundamental
mechanical properties of concrete were investigated by multi-scale simulation. At the mesoscopic scale,
a damage constitutive model was developed in accordance with the Mori-Tanaka homogenization theory
and progressive damage theory to predict the composited material properties of BFRC. At the macroscopic
scale, the obtained material properties of BFRC from mesoscopic were input into the fi
