The scope of the present paper is to show that energy dissipation on the curvilinear fracture surface prevails over energy dissipation in the bulk cementitious material, due to permanent deformation, friction and interlocking, when relatively small aggregates and large structural elements are considered.(A) For the covering abstract of the conference see IRRD 829348.
