Shear Strength Components of Concrete Under Direct Shearing

Direct shear tests on concrete specimens were conducted to investigate shearing behavior of the material under varying normal confining stresses. Results were analyzed to quantify the mobilization of shear strength components derived from hydrated cement paste–aggregate adhesion, contact friction, shear dilation, and cement–aggregate interlock along sheared surfaces under direct shearing. It was found that each component has a unique response in terms of mobilized shear stress and displacement. In addition, different failure modes observed in uniaxial compression, splitting tension, and direct shear tests were identified to delineate the Mohr–Coulomb failure envelope for shear strength of concrete material.
