Valoración de propiedades físicas del pet y maderas como alternativa para el uso en fortificación minera

Abstract:

This work aims to determine if recycled polyethylene terephthalate (PET), with the addition of fine aggregates (sand), is an effective alternative to the use of wood, in fortification structures in small underground mining, evaluating the physical properties of compressive strength, flexural strength, buckling strength and shear strength. To achieve this purpose, it was necessary to design and manufacture test tubes made of recycled PET and a reinforcing load of sand used for construction, as well as test tubes of the most used woods for fortification, eucalyptus, teak and pine. The respective data and calculations allowed the elaboration of technical sheets in which the composition, characteristics and observations that were collected from each sample prepared and treated are described. The results are conclusive in the different physical properties and recommendations are made for a new stage of investigation.
