摘要
This paper mentions two major studies on the delamination of external wall tile structures. External wall tile structures are usually made of tile, adhesive mortar, and concrete, and the interfaces between layers are considered to be a weak location against delamination. First, from the viewpoint of reaction, the heating experiment of a small scale tile structure was conducted. The temperature distribution in the through-thickness direction was measured with a thermography, and, based on the measured temperature, the stresses at the interface are estimated with simple analytical models. Next, from the viewpoint of resistance, the measurement of interfacial fracture energy and fatigue strength between concrete and polymer cement mortar were carried out. The interfacial bond strengths and their S-N diagrams are obtained. Based on the studies of reaction and resistance, the mechanisms of interfacial failure observed in external wall tile structures are discussed in order to achieve the durability of the interface and the tile structures.
