Simulation of Adhesion Performance of Mortar-Mortar Interface with Varied Fractographic Features

This paper aims at revealing the relationship between fractographic parameters of the mortar-mortar interface and the mechanical properties of such interface in terms of flexural strength and fracture energy. The FEM simulation was conducted where 8 cases of the combination of material properties were applied for all 7 interface models. The fractographic parameters evaluated on each interface model were six. Among them, both Sd (standard deviation of the height) and RL (ratio of the real length of the crack path to the projected length) are closely related to the mechanical properties.
