Destructive and nondestructive tests formulation for concrete containing polyolefin fibers

Abstract Polyolefin fiber is a new type of that was used in concrete to improve some the poor properties including; tensile strength, ductility, and fracture energy. In this research, contribution improving hardened examined by adding polyolefin fibers mix with different content. The polypropylene were added as ratio 0.5, 0.75, 1.0, 1.5, 2% volume. Destructive non-destructive tests carried out: slump, compression, splitting, bending, Schmidt Hammer, ultrasonic pulse velocity tests. results showed that, content increases, workability reduces dramatically. experimental findings demonstrate strength ductility improved small improvement overall compressive strength. show increased gradually increase up 1.5%, then, starts decrease. However, increases continuously increasing. A good relationship obtained between destructive nondestructive
