PHYSICAL AND MECHANICAL CHARACTERIZATION OF THE BAMBOO SPECIES DENDROCALAMUS ASPER

Abstract

The search for sustainable raw materials is increasingly necessary, especially for the civil construction sector, which commonly uses non-renewable materials with a high negative impact on the planet, such as steel and concrete. Therefore, the importance of exploring and studying regional natural resources that are renewable and sustainable to meet the demands of different sectors is highlighted. In this sense, bamboo, which has been a material used for millennia, presents aspects that fit this profile, but its characteristics change depending on the species and where it is grown. Considering this, this work is about the physical-mechanical characterization of the bamboo species Dendrocalamus asper, adapted to the climate of the northwest region of Paraná (Brazil) and the soil of the Arenito Caiuá (Caiuá Sandstone) formation, as a sustainable natural material. This characterization was carried out through laboratory tests based on the ABNT NBR 16828-2 (2020) standard, which obtained values for density, shrinkage, compressive strength parallel to the grain, tensile strength and tensile modulus of elasticity parallel to the grain. The results of these tests were statistically processed and analyzed, showing a satisfactory pattern when compared with the results of other researchers, and can therefore be used as a basis for analysis and evaluation of the potential of this bamboo species as a material for civil construction and several other sectors.
