The role of aggregate in the fracture of concrete

The fracture of concrete is reviewed. Tests on notched and unnotched beams made from concretes containing aggregates of different sizes and types are described. A simple model is proposed to elucidate and formalize the role of the aggregate particles in a brittle matrix. It is concluded that aggregate particles cause cracks to form in a concrete matrix at a lower stress than that at which the matrix would crack if it contained no aggregate. It is also concluded that aggregate particles impede the extension of matrix cracks.
