    to make highstrength concrete, it is easier to do so with coarse aggregates below mm (Y, in.) (ACI 36395). There has not been much research on the effects of coarse aggregate content on the fracture energy of concrete. One study, conducted by Moavenzadeh and Kuguel (1969), found that fracture energy increases with the increase in coarse aggregate content. Since cracks must travel around ...
