Sustitución del agregado fino por Policloruro de Vinilo en el concreto estructural

Abstract

Este artículo es de tipo experimental, ya que se evaluó el comportamiento que tiene el concreto estructural al agregarle PVC en sustitución del agregado fino en un 20%, 30% y 40%. Se determinaron las propiedades físicas del policloruro de vinilo (PVC) y los agregados (fino y grueso), obteniendo que el peso específico del PVC es de 1.14 gr/cm3 y del agregado fino es de 2.59 gr/cm3. Se hicieron pruebas de granulometría, peso específico, contenido de humedad, resistencia a la compresión, flexión y tracción. Del mismo modo se desarrolló un concreto patrón y concretos reemplazando el agregado fino en ciertas cantidades de PVC triturado. Como resultado de los ensayos de resistencia a la compresión se tiene que para el concreto patrón la resistencia es de 242 kg/cm2, para un concreto teniendo un 20% de PVC es de 214 kg/cm2, para un 30% de PVC es de 209 kg/cm2 y para un 40% de PVC es de 153 kg/cm2. Para la prueba de resistencia a flexión a mayor porcentaje de PVC la resistencia tiende a disminuir, pero estando dentro de los límites permitidos de la norma técnica.

This article is of an experimental nature, since the behavior of structural concrete was evaluated by adding PVC to replace the fine aggregate by 20%, 30% and 40%. The physical properties of polyvinyl chloride (PVC) and the aggregates (fine and coarse) were determined, obtaining that the specific weight of PVC is 1.14 g/cm3 and that of the fine aggregate is 2.59 g/cm3. Tests were carried out on granulometry, specific weight, moisture content, compressive strength, flexural strength and tensile strength. In the same way, a standard concrete and concretes were developed by replacing the fine aggregate with certain quantities of crushed PVC. As a result of the compressive strength tests, for the standard concrete the resistance is 242 kg/cm2, for a concrete with 20% PVC it is 214 kg/cm2, for 30% PVC it is 209 kg/cm2 and for 40% PVC it is 153 kg/cm2. For the flexural strength test, the higher the percentage of PVC, the resistance tends to decrease, but is within the limits allowed by the technical standard.
