| Abstract: | Ultra-high performance fiber reinforced concretes(UHPFRC) with compressive strength over 100 MPa were confected by using steel fibers,such as kink end type,flat end type and wavy type.Doped fiber volume ratios were 1.0%,2.0%,2.5% and 3.0% respectively.The influences of steel fiber shapes and doped volume ratios on the fluidity,compressive strength,flexural strength,fracture energy and bending toughness of UHPFRC were researched through cube compressive tests and beam flexural tests.Experiment result shows t... |
