Diseño de casetones y muros no estructurales con botellas PET para la construcción de obras civiles

Abstract

In many countries, expanded polystyrene (styrofoam) have been strongly questioned in recent years due to the risks it represents not only for the environment but also for human health due to the long decomposition time, the negative impacts generated on the environment., its short lifespan as its recycling price is low. PET containers are another problem that affects the environment every day because large amounts of this waste are generated, a small part of which is recycled and the rest are sent to landfills or simply are discarded on the ground or in the tributaries. For the development of this document, an investigative methodology was implemented. Due to the little application of PET containers as an alternative material in civil works, allowing the caissons and non-structural walls to present positive results due to their environmental focus. To establish the reliability of the cassettes, compression tests were carried out with loads supporting weights between 155.2 Kg and 254.2 Kg without presenting great damage, and with the universal compression machine, tests were carried out with different types of dimensions, giving that the larger ones had Results of 30KN at its maximum point, for non-structural walls laboratory tests were not carried out for axial load, but the different forms of anchoring that guarantee the stability of the walls were taken into account. Consequently, the purpose of this research is to reduce the use of expanded polystyrene used as caissons for lightening mezzanine slabs and as a core in lightened walls, by creating caissons and non-structural walls with PET containers, which allows to carry out this material and reduces the use of styrofoam, in addition to obtaining a competitive price of $ 35,667 per m3 for the caseton prototype and $ 96,805 for the non-structural PET wall.
