Abstract: Strain resilient cementitious composites (SRCC) is a class of ECCs; their high deformation capacity as a result of the fiber reinforcement along with the limited porosity render these concretes as highly durable materials with increased cracking resistance. In this experimental study four SRCCs were made with Greek unclassified calcareous fly ash (FA) and polypropylene (PP) fibers. Two contents per each ingredient were studied aiming to produce sustainable concrete of adequate strength and toughness: fly ash was added in two and three times per weight of cement and fibers in 1.5% and 2% per volume. The mechanical characterization was assessed in regards to the compressive response at 28 days. The materials volumetric stability was measured at ambient conditions aiming to investigate the drying shrinkage effect.
