EVA Lightweight Concrete Reinforced with Piassava Fiber

Abstract:

The residue of Ethylene-Vinyl Acetate (EVA) generated in the footwear industry is an economic and environmental problem as it requires large area for storage in landfills and is not biodegradable or capable of transformation into other polymers. Its use as a lightweight aggregate in mortar and concrete results in a material with lower density but with reduced strength. In this paper, piassava fibers (Attalea funifera Martius) were used as reinforcement of lightweight concrete containing 4% and 6% of EVA, with the goal of improving the flexural strength of the material. The determination of density, compressive strength and flexural strength were performed at 28 days of age. The experimental results demonstrate that the addition of EVA decreases the density and flexural strength of the concrete in proportion to the amount of addition, but a recovery resistance is obtained when the piassava fibers are added in amounts of 1 to 2% by volume.
