Measurement of Concrete Surface and Evaluation of Bond Property

We measured the roughness of concrete surface, and estimated quantitatively the roughness in concrete surface by using six indexes. Then, we investigated the relationship between the roughness of concrete surface and the bond strength at the bond surface. The surface were measured by using 3D measurement system with slit-laser and CCD camera developed in our laboratory. Slant shear test was used to evaluate the bond property. To investigate the availability of 3D measurement system with CCD camera and laser beam is also a purpose of this study
