Fiber- reinforced bond mortar is a term used when mortar is strengthened with haphazardly dispersed short fibres. The fundamental destinations of the paper were to examine the impacts of short-fiber on auxiliary concrete mortar of used polypropylene. The practices of plain bond mortar and fiber- reinforced cement mortar are thought about. Finally, information for the new and solidify properties if the cement mortar were gathered and investigated. The extent of this investigation depends on the use of polypropylene short-fibres. To assess the impacts of polypropylene short-fiber on the flow ability of reinforced mortar. An investigational consider was led on the cement mortar reinforced by the diverse rates of polypropylene short fiber (0, 0.5,1 and 1.5%). The fundamental goal of this work is to contemplate the mechanical properties of cement mortar containing diverse rates of polypropylene short fiber. Diverse tests have been done to decide a few perspectives in particular the droop test and compressive strength at period of curing 28 days was led on reference and polypropylene short-fiber strengthened mortar examples. The outcomes demonstrated that the use of polypropylene short-fiber gives a change in these properties. The outcomes demonstrate a noteworthy expanding in compressive strength with the augmentation of short-fiber content in cement mortar.
