In the present work, the effect of microcracks present at the interface of coarse aggregates and cement mortar in plain concrete is studied with the aid of micromechanics. The presence of microcracks affects the macroscopic response of cementitious composites to a great extent. The conditions under which the cracks propagate along the interface or kink into the cement matrix are investigated. Homogenization schemes are employed to obtain the overall behavior of the composite material under uniaxial tensile loading conditions.
