Concrete is strong in compression and weak in tension. So when we provide the reinforcement to the concrete majorly steel is used as the reinforcement. Many of the researches are in progress to find a substitute to this material. Many investigations proposed artificial fibers. In this project we would like to take the naturally available fiber named sisal fiber is taken as a substitute material to the reinforcement and study the properties. The results show that the composites reinforced with sisal fibers are reliable materials to be used in practice for the production of structural elements to be used in rural and civil construction. This material could be a substitute to the steel reinforcement which production is a serious hazard to human and animal health and is prohibited in industrialized countries. The production of sisal fibers as compared with synthetic fibers or even with mineral asbestos fibers needs much less energy in addition to the ecological, social and economical benefits. Then the sisal fibered concrete is compared with the mechanical properties of the polypropylene fiber and shown the comparison between the both fibred concrete. In this investigation the fiber is added to the concrete to study the properties of the fiber reinforced concrete, the addition is about 0, 0.5, 1, 1.5, 2 percentages by weight of concrete for the relative mixes using sisal fiber. A special mix is done using 0.5% for the polypropylene fiber. This work continues with the testing of concrete specimens in addition with sisal fiber and polypropylene fiber, the mechanical and transport properties of concrete were tested i,e compressive test, split tensile strength, evaporation test, water absorption test, water absorption test
