Elaboración de un hormigón polimérico aprovechando residuos de la trituración de placas electrónicas

Abstract

The aim of this research is to describe the manufacturing of a polymeric concrete using regional materials such as: polyester resin (and its chemical admixtures), stone aggregates from Pifo´s quarry, shredded electronic boards waste, this last one as partial replacement of resin and also for reducing the environmental impact of this waste. In order to accomplish it, five polymeric concrete mixtures were developed by the optimal density method, in which proportion of stone aggregates were fixed while resin mass (with its chemical admixtures) and PCB waste were changed by increasing in 0 (std), 5, 10, 15 and 20% of PCB waste in replacement of resin. Cylindrical samples were tested for compressive strength at ages of 1, 3 and 7 days and other prismatic samples of polymeric concrete were tested for flexural strength. In conclusion, the best mechanical performance was reached by the mixture with 5% of waste replacing resin, which developed almost 100 MPa of compressive strength and 23.4 MPa of flexural strength.
