Destructive and Nondestructive Tests for Concrete Containing a Various Types of Fibers

Fibers have been considered an effective material that was used to improve the concrete's weak properties, namely its tensile strength, ductility, and crack resistance. Thus, current study highlights two major objective, former is fibers shapes types on mechanical properties of fresh hardened concrete while latter explores impact fiber contents developments. To achieve these targets six (five them made steel last polyolefin fibers) with various are utilized. The tests were carried out investigate shape contribution in mix improvement. samples subjected destructive non-destructive such as workability, compression, bending, splitting. include ultrasonic pulse velocities Schmidt Hammer test. Three kinds (two one fiber) variable content ratios 0.5, 0.75, 1.0, 1.5% effect. Generally, workability has a reverse relationship presence ratios. compressive capacity, splitting flexural strength direct proportion contents. hooked appeared best results terms comparison.
