Resumen:
The present work presents an alternative of reuse of polyethylene terephthalate
(PET) bottles in the replacement of the small aggregate of mortars, which can
help reduce costs and increase the recycling rates of this material, thus
reducing the environmental impact caused by the disposal The same. Since
PET bottles have shown a lot of mechanical and thermal resistance, which
makes them strong candidates for use in the construction industry. Due to the
high growth of the consumption population and also the difficulty of
decomposing this material, the use of this waste as raw material has been
adopted as a solution to the serious environmental impacts, especially in urban
and marine areas. This work aims to determine the absorption by water
immersion of incorporated mortar with contents of 10% and 15% of micronized
PET, through the molding of specimens for each content. Thus it is necessary
to define the changes that this incorporation will entail in the water absorption of
these mortars. According to the results obtained, there was an increase in the
water absorption by the specimens as the PET content increased, indicating
that the use of micronized PET in the mortar composition causes a greater
permeability with a Possible increase in the void index of the material, thus
providing a greater uptake of water through its surface.
