Análisis de las propiedades mecánicas de especímenes de hormigón fabricados con partículas de reciclados en sustitución a porcentajes de agregados.

Abstract

Abstract:This project presents the results of evaluating the mechanical properties of concrete specimens made with recycled particles in substitution to percentages of aggregates. The recycled rubber and plastic particles were obtained from the companies ECSADE S.A. and Juan Álvarez located in Guayaquil and Cuenca respectively. Aggregates from the quarry of the city of Catamayo, located in the province of Loja, were used to manufacture concrete beams and cylinders in order to evaluate the resistance to bending and compression. For the manufacture and mechanical characterization, a concrete was designed with substitution of 0%, 5%, 10%, 15% of rubber particles and plastic in replacement of the fine aggregate for a resistance of 21MPa after 28 days of curing. Based on the results, the compressive strength decreased by 9.36% and the flexural strength decreased by 2.24% with respect to the standard concrete in substitution of plastic particles. It was determined that the use of recycled particles increases the reveniment of fresh concrete.
