In the past few decades, some researches have been devoted to use of plastic fibers and other waste materials as additive materials in concrete in order to improve the tensile and compressive strength as well as ductile properties of concrete. Due to these effects this experimental work was undertaken aiming to investigate the behavior of Plastic fibers concrete and barley straw fibers concrete by using readily available local materials. To accomplish the objective, experiments were conducted on plastic fibers concrete and barley straw fibers concrete. The principal variable of the testing program is the amount (percent by weight) of plastic fibers and barley straw fibers which used as replacement of fine aggregate by the following ratio at (0.1%, 0.5%, 1%, and 2%) by weight respectively. Specimens were prepared and tested under standard specification for slump, and compressive strength. The result of the study indicated that the fresh concrete was good enough workable up to 0.5% replacement of plastic fibers. On the other hand the present of barley straw fibers results in decreasing the workability for all replacement ratios. The addition of plastic fibers to concrete mix results in improvement of the compressive strength for the concrete mixture up to ratio (1% or less) of plastic fibers. But adding barley straw fibers in concrete mix has a significant effect on decreasing the compressive strength of concrete.
