In cementitious materials, bonding at the contact surface between cement-paste and coarse aggregates plays an important role and determines the durability of the material. Recent studies have evaluated the impact strength on this contact surface by experiments on different surface roughness aggregates and concluded that the contact area between the two components was the weakest zone in concrete. This paper presents experiment test on cement-paste and cobblestone contact surface to determine the types of damage modes using Acoustic Emission Technique. The result is that the shear stress occupies only about 10% of the total stress experienced on the contact surface.
