The aim of this paper is to present preliminary results regarding Engineered Cementitious Composites (ECC) and their behaviorwhen experimentally assessing their fracture energy, bymeasuring the flexural tensile strength (limit of proportionality, residual). As a characteristic of a ductile material, fracture energy is an important parameter when assessing ECC post-cracking residual stresses. With 2% fibers addition in the mixtures, the crack width can be controlled and the material's ability to bear a tensile strain-hardening capacity has been assessed. Ninety days flexural tensile strength tests were performed in order to obtain preliminary results on ECC prismatic specimens. [ABSTRACT FROM AUTHOR]
