Characterization of the Mechanical Properties of Concrete with Addition of Bamboo Fiber - Porto Nacional/TO

Abstract

The search for materials which do not unduly the environment by reducing the cost of production is increasing throughout the world. In the construction sector, concrete is the most consumed material in the world. Its production with bamboo fiber addition can contribute to minimize environmental impacts and production costs by reducing the extraction of natural resources. This study aimed to investigate the mechanical properties of bamboo located in the region of Porto Nacional - TO, Brazil and its application as a binder (Portland cement) in the production of concrete. The research aimed at results that allowed to verify the behavior of the concrete in relation to its uniaxial compressive strength at 28 days of the specimens produced with the addition of bamboo fibers, replacing the cement binder. Bamboo fibers and aggregates were characterized and evaluated according to the material and defined by the trait (1: 1.68: 2.68: 0.482), with replacement percentages set at 3%, 4% and 5%. Therefore, through the tests that were performed, the possibility of replacing the Portland cement binder with natural polymeric bamboo fibers was verified, which proved to be viable and quite advantageous not only for the environmental and economic, but also in the material strength gain.
