Determinação da absorção de argamassas incorporadas com PET micronizado.

Abstract

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.
