Tijolos de adobe com adição de bagaço de cana de açúcar

Abstract

Brazil has a housing deficit that affects mainly low-income families. However, financing options for construction systems that are not in line with the conventional ones are still little discussed, as there are no specific credit lines for them. One of the justifications is that there is no standardization of techniques. In this way, this work had the objective of determining and comparing the compressive strength of adobe bricks with different percentages of sugarcane bagasse addition and verify if in the resistance question it adapts to the standard for masonry of the fence. Soil and fiber characterization tests were carried out; (0%, 10%, 20%, 30%, 40% and 50%) of sugarcane bagasse fibers; and determination of the resistance to axial compression. The soil was classified as sandy. From the results of axial compressive strength, only the adobe with percentage of 0% of fibers could be analyzed, with a mean of 2.02 MPa. The others did not present a rupture curve. The results can be used as a parameter to enable the use of adobe brick in public policies of bank financing. For its characteristic resistance meets the Brazilian norms for masonry of fence, as well as attested by other literatures.
