The present research proposes the application of recycled materials in the construction industry, which is a contribution in the concept of sustainable constructions for the environmental benefit, for example the reuse of plastics. The applications of recycled materials in the use of PET (Polyethylene Terephthalate) recycling from discarded bottles which is not a good final disposal and generates pollution by accumulation and slow degradation. In this research the influence of recycled PET fibers as a reinforcement on a cement matrix was evaluated, cement mixtures were produced to ASTM C31 using Portland cement, coarse sand and stone of ½” with additions of recycled PET fiber at different percentages: 0%, 0.5% , 1.0% and 1.5%. The mixing design considered a water / cement ratio: a / c = 0.62 and a required compressive strength of 210 kg/cm2 for prefabricated applications such as: floor tiles, benches, perimeter fences and stoptires for parking the specimens were subjected to tests of compressive strength and Splitting tensile strength in periods of 28 days of curing for hardened state and Slump in the fresh state The results revealed that the presence of PET fiber in the concrete decreases the performance of the concrete since the compressive strength decreases as the percentage of PET fiber in the mixture increases. The maximum percentage of PET fibers for a desired yield of the concrete was 0.5% for which compression and Splitting tensile strengths of 232.47 kg/cm2 and 25.9 kg/cm2 respectively were obtained, as well as a 2.9 " Slump which allows the accommodating the mixture during its formation
