Abstract

In the present paper, the fracture behaviour ofroller-compacted concrete specimens isexamined. Such specimens are reinforced withdifferent types of steel and polypropylene fibresrandomly distributed in the cementitious matrix.The Modified Two-Parameter Model, proposedby the authors, is employed to compute thecritical stress intensity factor (fracturetoughness) taking into account the possiblekinked crack occurring during the stable crackpropagation.
