Abstract
The effects of the surface condition on the shear bond properties of concrete joints were investigated through compression tests. The bond properties of concrete joints at 60 degrees to the horizontal axis, which were treated in different ways, were able to be characterized with the peak load and the area under the load-displacement curves. The shape of the load-displacement curve of the post peak load was more sensitive to the joint surface treatment than the peak load. The acoustic emission (AE) technique was applied to the shear bond properties of the concrete joints. The results of the location of AE event sources depended on surface conditions. The AE technique gave us detailed informlation about fracture properties of concrete joints.
