Comportamiento a flexión del hormigón tradicional frente a un hormigón en base a PET reciclado y fibras de bagazo de caña de azúcar

Abstract

In this experimental work the reuse of materials as they are proposed; recycled PET plastic and cane bagasse fibers, which replace a percentage of the total weight corresponding to coarse aggregate, in the dosage and elaboration of traditional concrete beams. The technical, economic and environmental behavior of the proposal was analyzed through controlled bending laboratory tests and its cost comparison of these alternative materials compared to traditional ones in the local market. Technically, it was found that the traditional concrete specimens reinforced with 5 and 7 percent recycled PET plastic have mechanical properties according to the NTE-INEN standard for non-structural elements. The cane bagasse fibers did not meet the standards, with a maximum of 1.5 percent fiber addition being the best result. The economic analysis showed that concrete with PET reinforcements is competitive with traditional concrete.
