摘      要：Self-compacting concrete(SCC)is a type of concrete which is frequently preferred in different applications due to its advantages such as its fluidity and transition in tight openings between steel reinforcing ***,it is vital that SCC maintains its fresh state characteristics when its transportation phase is taken into *** reinforced in SCC affects the properties of fresh concrete negatively while it had a positive effect on its dynamic *** this study,the effect of steel fibers having different aspect ratios on the time dependent fresh properties and mechani-cal properties of self-compacting concrete mixtures was *** addition to the control mixture without fiber,in the mixtures containing fiber,three different twin-hook steel fibers with aspect ratios of 54,64 and 50 were used as 0.6%of total *** all of the SCC mixtures,the water/cement ratio,cement dosage and slump-flow value were kept *** time dependent rheological properties of the mixtures were *** compressive,split-tensile and flexural strengths as well as fracture energy,the load deflection relation under flexural load and load-crack opening displacement,modulus of elasticity of SCC mixtures were also ***,the water absorption capacity and depth of penetration of water under pressure of mixtures were *** the basis of the results,the fiber utilization and its aspect ratio had no significant effect on compressive strength and modulus of elasticity of the SCC *** split-tensile,flexural strengths and fracture energy of SCC mixtures increased by using fiber;the permeability properties of SCC mixture increased by fiber utilization.
