| Abstract | Steel fibers having different lengths and volume fractions were introduced into the concrete and the properties of the fiber concrete namely the workability, compressive strength and modulus of rupture were investigated. Based on the results obtained, an appropriate combination of fiber length and volume fraction was selected for use in casting precast prestressed concrete beams. Two prestressed fiber concrete beams as well as two prestressed plain concrete beams were observed with regard to their performance at the stage of prestress transfer and under third-point loading. The tests showed that fiber length and volume fraction are the two important factors influencing the workability and strength of the fiber concrete. The use of steel fibers in the prestressed concrete beam resulted in a decrease in the midspan camber at transfer of prestress and an increase in the post-cracking flexural stiffness. |
