| Popis: | The main objective in this investigation is to study the structure-property relation of fiberreinforced composites fabricated with Portland cement paste and sugarcane bagasse fibers, which is a residual biomass resulting from the cleaning, preparation, and extraction of sugarcane juice. Pastes of 1.0 and 2.0wt% of fibers were manufactured with water to cement ratio (W/C) of 0.6. The mechanical properties were determined through three-point flexion tests and the microstructural characterization was carried out through Scanning (SEM) tests. A performed. Density, compressive strength, and ductility graphs were included. An analysis of the influence of capillaries pore size of the fiber over the flexural strength was made. Results show that the improves the compressive strength, 9.7MPa, 8.8MPa and 11.5MPa for cement paste with 0, 1 and 2 wt% fibers contents, respectively. These composites can be used as alternative green materials for houses in areas were sugarcane bagasse has poor or none . |
