Paper Title:
Bonding Mechanism of Horizontal Construction Joints
  Abstract

The quality of construction joint is significantly influenced by the precision in the concrete placement. In order to obtain the mechanical properties of horizontal construction joints surface, a comprehensive research was conducted. The research focused on the tensile capacity and seismic behavior of construction joints surface. According the tests failure characteristics, four kinds of cracking model of construction joints zone were formed. Test results indicated that bond materials could increase displacement ductility more than 10%~30%. And the clamping action provided by bond materials was so good that failure didn’t occur at the construction joint itself, but in the concrete adjacent to it. Axial compressive force is advantageous for the shear capacity of construction joint interface.
