Abstract

To investigate the shear performance of the interface between concrete and stone, the interfacial shear test of concrete - stone carried out by using the Z-type and hoop-type specimens. The effects of different bonding methods, material strength and different forms of embedded steel bars on interfacial shear properties are considered.. The experimental results show that the bonding interface between concrete and stone is the weak point of the sample, and the damage occurs on the interface. The fracture pattern of Z-type specimen is vertical crack and diagonal crack near the interface. The crack forms of the hoop type specimens are the diagonal cracks distributed on the top of concrete, vertical and oblique cracks on the sides. Within a certain range, the strength g of the concrete will increase the shear strength of the interface and delay the cracking of the specimen. When the strength grades of concrete were C35, C40 and C45, the shear strength of the Z-type specimen increased by 14.7% and 10.8% respectively, and the shear strength of the hoop-type specimen increased by 15.2% and 11.1% respectively. Interfacial implantable steel bar can improve the shear resistance of interface significantly, and the greater the rate of steel bar, the greater the shear strength. When the planting rates were 0%, 0.196%, 0.392% and 0.785% respectively, the improvement rates of shear strength of Z-type specimens were 40.2%, 65.5% and 45.2% respectively, and the improvement rates of shear strength of hoop specimens were 64.1%, 54.5% and 60.5% respectively. The shear strength of the hoop type specimen is greater than that of the Z-type specimen, the non-planted bar specimen is increased by about 20%, and the planted steel bar specimen is increased by about 40% to 55%.
