Publication Name Effect of Volume Fraction of Fine Aggregate on the Mechanical Properties and Impact Resistance of HSC and FRC
Publication DescriptionThis paper presents the results of an investigation on the effect of volume fraction of fine aggregate (VFFA) on the mechanical properties and impact resistance of high strength concrete (HSC) and fiber reinforced concrete (FRC). Five values of VFFA ranged from 33.33 to 66.67 are chosen. The impact resistance of four different coated materials is also examined in the present work. The optimum value of compressive and indirect tensile strength of FRC is obtained at specific surface area (SSA) of combined aggregate equals 28 cm2/gm. However, the strength of HSC decreased with increasing SSA of combined aggregate.
ACI drop-weight impact test failed to show the effect of VFFA on the impact resistance of HSC and FRC. ACI drop-weight impact test failed again to compare between the different coated materials. In general, FRC showed higher resistance to first crack and failure than those of HSC without and with coating.
