Abstract

Simple methods for evaluating the effect of the degree of surface treatment at construction joints on their shear bond properties were investigated. Uniaxial compression tests were conducted, in which axial compressive forces are applied to rectangular specimens having slant construction joints with different joint angles and degrees of surface treatment to cause normal and shear stresses at the joints. When the joint angle is 60°, it was possible to evaluate the effect of the degree of surface treatment on the shear bond proper- ties by determining and comparing the peak loads and consumed energy expressed by the areas under the load-displacement curves. AE source location and AE parameter analyses were also conducted to investigate the fracture process of these jointed specimens.
