This paper investigates on analyzing the effects of use of Polypropylene fiber in the mechanical properties of cement mortar. An experimental study was conducted on the cement mortar reinforced by the different percentages of polypropylene fibre (0, 0.5,1 & 1.5%). The essential objective of this work is to study the mechanical properties of cement mortar containing different percentages of polypropylene fiber. Different tests have been done to determine some aspects namely the flow table test and compressive strength at age of curing 28 days was conducted on reference and polypropylene fiber reinforced mortar specimens. The results show that the use of polypropylene fiber gives an unambiguous improvement in these properties and thus the optimum percentages for this fiber have been taken into consideration. The results show a significant increasing in compressive strength with the increment of fibers content in cement mortar.
