HPFRCC(High performance fiber reinforced cementitious composite) have made major advances in recent years, to the point where they are being adopted in building and bridge constructions. The most significant advantage of HPFRCC over conventional concrete is their high tensile ductility. But HPFRCC reduced economic efficiency due to silica sand and short fiber of expensiveness to exhibit strain-hardening accompanied by multiple cracking. This study is a part of series of researches to replace silica sand in HPFRCC to fine aggregate. The objective of this study was to investigate the compressive strength properties of HPFRCC according to fine aggregate size under cyclic loading for using fine aggregates as substitution of silica sand. As fine aggregate size are bigger, compressive strength and elastic modulus of PVA and PE HPFRCC were decreased under cyclic loading within the scope of this research.
