摘　　要：The concrete mixed to sugarcane bagasse fibers and polypropylene fibers prepared with varied conditions were presented. The aim of our study is to formulate a concrete mixed with sugarcane bagasse fibers, which will gradually replace the conventional polypropylene fibers often used. We formulated all our concretes using the dreux gorisse method. We used an oven calibrated at 105˚C to dry the washed fibers. We also carried out tensile splitting and compression tests, at 28 and 112 days of age. The reinforcement mechanisms of sugarcane bagasse fibers and polypropylene fibers concretes were subjected to tensile splitting and compression tests after total immersion of the specimens in tap water at 28 and 112 days. Porosity at 28 days, mass loss and drying shrinkage at 80 days were also studied. The curing processes of concretes containing 0.10, 0.15, 0.17, 0.23 and 0.25% bagasse fibers were compared with those of ordinary concretes containing no fiber. The results showed that the addition of bagasse fibers reduces mechanical strength and porosity. In summary, specimens SBC-0.15 and SBC-0.17 showed the best results for all fibers. We plan to do the same work, but this time with raffia or palm nut fibers.The concrete mixed to sugarcane bagasse fibers and polypropylene fibers prepared with varied conditions were presented.
