Análisis del comportamiento del hormigón mediante la adición de tereftalato de polietileno reciclado.

Abstract

Ecuador has been greatly affected by its high percentages of single-use plastic waste, thus generating great damage to the community. The purpose of this research is to propose a solution in which polyethylene terephthalate, a material used in the manufacture of bottles, will be used as a partial replacement of the fine aggregate for the concrete mix. The applied methodology consists of the elaboration of concrete specimens where comparative tests will be carried out between a traditional concrete mix and a concrete mix with the additions of different percentages such as 0.5%, 1%, 2%, 4%, 6% and 8% of recycled polyethylene terephthalate flakes, analyzing and demonstrating its behavior and benefits to consider it as a new construction method. The results obtained from the study indicated that the lower the percentage of sand replaced, the higher the compressive strength of the element, it was determined that the replacement of 0.5% - 1% of the PET aggregate with respect to the fine aggregate, there is a better compressive performance, since, from 2% onwards, the results were not expected.
