Shear Strength Behavior of Crude Oil Contaminated Sand-Concrete Interface
Abstract: A laboratory
investigation into crude oil contaminated sand-concrete interface behavior is
performed. The interface tests were carried out through a direct shear
apparatus. Pure sand and sand-bentonite mixture with different crude oil
contents and three concrete surfaces of different textures (smooth, semi-rough,
and rough) were examined. The experimental results showed that the concrete
surface texture is an effective factor in soil-concrete interface shear
strength. The interface shear strength of the rough concrete surface was found
higher than smooth and semi-rough concrete surfaces. In addition to the
texture, the normal stress and the crude oil content also play important roles
in interface shear strength. Moreover, the friction angle decreases with
increasing crude oil content due to increase of oil concentration in soil and
it increases with increasing interface roughness.
