Shear Behavior of Sensitive Marine Clay-Concrete Interfaces

This paper presents the results of an experimental study on Leda clay-concrete interface shear behavior. Leda clay specimens with various dry densities and salt contents are used to study the influence of these parameters on the interface shear behavior. The results indicate the following: (1) interface shear resistance increases as the concrete surface roughness increases; (2) increasing the dry density of remolded Leda clay enhances its interface shear resistance; and (3) a higher salinity of Leda clay pore water results in higher interface shear strength.
