Resumen
Polyethylene terephthalate (PET) waste and its low recycling rate contribute to the detriment of the environment, it is therefore necessary to use PET waste in different ways, for example as precursor materials in concrete preparation. This work presents the preparation of concrete with pelletized and non pelletized PET waste as replacement by volume of 1.7%, 3.4% and 5% of fine aggregates. An increase of pelletized and non-pelletized PET waste was directly and inversely to slump, respectively. The density decreased with the increase in replacement content in pelletized and not pelletized PET waste. The concrete prepared with pelletized PET exhibited the highest compressive strength, being the concrete mix containing 1.7% of pelletized material, the one that exhibited the highest compressive strength (96% of the traditional material). Furthermore, the mixtures containing 1.7% of non-pelletized material achieved a lower compressive strength (76%). Based on the results, the prepared concrete containing pelletized PET waste presents a solution to plastic waste disposal.
