Mechanical behavior of cementitious composites reinforced with the fiber of sugarcane bagasse and glass wool waste

The use of natural fibers and powdered glasses can improve the mechanical properties of the concretes and increase the cracks resistance generated by tensile and concrete stresses. Thus, the aim of this paper is to evaluate the mechanical behavior of concrete with the addition of fibers of sugarcane bagasse and/or glass wool. Physical, chemical and morphological characterizations were performed. Sugarcane bagasse was chemically treated. Concretes were produced containing additions of ground glass wool and/or fibers of sugarcane bagasse cured in 28 days. The results of this research showed that the exclusive addition of glass wool (10%) in concrete contributed to higher values of compressive strength, flexion tensile and diametrical compression tensile, reaching 34.22 MPa, 6.65 MPa and 16 .44 MPa, respectively. The ground glass wool contributed to the reduction in the concrete porosity (void index equal to 9.38%).
