Análisis y aplicación de la mezcla de hormigón con poliestireno expandido en detalles constructivos (mesones de cocina)

Abstract

This research focuses on examining the combination of concrete and expanded polystyrene. This specific mixture contributes to achieving a considerably lighter structure. In addition, its physical-mechanical characteristics are highlighted, providing adequate compressive, shear, tensile, and flexural strength and good elasticity. For the project, concrete cylinders were manufactured, mixing different percentages of polystyrene (5%, 10%, 20%, 25%, and 50%) to replace the fine aggregate, testing the strength ranges that this type of concrete must meet according to ASTM C-330. According to the results of the tabulated tests, following the procedures established by the ASTM C78 and ASTM C39 standards, the mix that was taken complies with the flexural strength ranges between 5.94 Mpa, and 15.37 Mpa, and has a lower weight than the usual concrete dosage. In this case, the mix within the range issued by the UNE-EN 12372 standard, meeting the mentioned criteria and having a lighter weight than other mixes, is concrete with 50% polystyrene. This mix will produce prefabricated slabs employed as kitchen countertops, forming part of a construction detail for any social housing, and could be used instead of granite.
