Materiales constructivos transformando basura plástica arrastrada por corrientes oceánicas : mitigación ambiental de las islas Galápagos.

Abstract

The use of ecologically friendly building materials has become one of the most important current trends, this is due to the need to reduce the environmental impact that aggravates the planet's situation, which is why the present experimental research work was carried out With a quantitative focus, it aimed to inform the manufacturing processes of construction materials, through the use of plastic marine litter dragged by ocean currents to the Galapagos Islands. To this purpose, he participated as a volunteer in the coastal cleaning day held on September 21, 2019 on Santa Cruz Island. The material collected during this day was transferred to the Solid Waste Management Plant, where the sampling and classification of the different polymers were carried out, these were taken to a chopper that reduced their size and facilitated the process of mixing with compatible additions, compacted the material in test tubes increasing the temperature to achieve stable, homogeneous and durable mixtures. These specimens were tested in the Laboratory Research Center in Resistant Structural Engineering (CEINVES), where the results of the behavior of the material were obtained at different efforts, at simple compression exceeded 300 Kg / cm2, at traction Indirect was 73 Kg / cm2 and obtained a breakage module of 190 Kg / cm2, data that are above the magnitudes of resistance typical of traditional construction materials, which allowed designing boards with dimensions of 290 cm in length, 20cm wide and 4cm thick, the same that can be manufactured in series and used as walls that are bolted to the columns of the same material for the construction of prefabricated scientific shelters in the Galapagos Islands.
