The current paper deals with the characterization of the mechanical behavior of both an HSC and HSFRC obtained by an appropriate mix design constituted by volcanic aggregates from the quarries of Eastern Sicily. The mix design was carried out on eight different concrete mixtures by using the theoretical model developed by Feret – De Larrard’s and it is capable of simulating the experimental compressive strength. The HSFRC mixtures consider different volume fractions of fibers equal to 0% (HRC), 0.5% and 2% (HSFRC). Straight Polivinyllialcohol (PVA) and hooked-end steel fibers were the two types of fibers employed in the study. Compression tests were carried out on specimens performed according to UNI codes. The HSFRC(0.5%) mixtures did not show great differences in mechanical performance by any variation of the fiber type (steel or PVA).

Abstract

The current paper deals with the characterization of the mechanical behavior of both an HSC and HSFRC obtained by an appropriate mix design constituted by volcanic aggregates from the quarries of Eastern Sicily. The mix design was carried out on eight different concrete mixtures by using the theoretical model developed by Feret – De Larrard’s and it is capable of simulating the experimental compressive strength. The HSFRC mixtures consider different volume fractions of fibers equal to 0% (HRC), 0.5% and 2% (HSFRC). Straight Polivinyllialcohol (PVA) and hooked-end steel fibers were the two types of fibers employed in the study. Compression tests were carried out on specimens performed according to UNI codes. The HSFRC(0.5%) mixtures did not show great differences in mechanical performance by any variation of the fiber type (steel or PVA).
