- Abstract
- It is necessary to involve the characteristics and quantitative surface treatment at the same time in order to retain oneness of
Ultra-High-Performance Concrete(UHPC) according to construction joint occurrence. Therefore, this study derives a reasonable surface treatment
method in a material's point of view through the shear adhesion performance evaluation according to the construction joints surface processing
method as a part for securing the adhesion performance of the construction joints when casting UHPC. 180 MPa of required average strength
was used for mix of UHPC and surface treatment method was set to totally 6 level that MN-0, AC-0, WJ-0, GR-10, GR-20, GR-30. After the
specimen were manufactured to a size of 300×640×150 mm, Push-off test was performed to evaluate the shear adhesion strength. As a results,
the bonding shear performance was increased when executing a surface treatment for the construction joint interface. As the increases in length
of grooves every 10 mm, the bonding shear performance increased about 2.3 times. In this study, it is judged that 30 mm of groove length
would have had an advantage for securing the monolithic of concrete. Also, the interface of cross section and the number of grooves should be
considered to increasing in the bonding shear performance of concrete.
