Natural fibers are becoming a key point for the development of new concrete mixes because these fibers are recovered from residual biomass. In this paper, we focus on the natural fib‘ers found in the Metropolitan District of Quito, Ecuador. For this purpose, we searched for materials (fibers) available in the Chemical Engineering laboratory at Universidad San Francisco de Quito USFQ. In this paper, we analyze different literature on how the use of fibers influences the mechanical properties of concrete. Based on this analysis and the materials at the laboratory, we have developed recommendations on which natural fibers are of interest for further experimental research. Furthermore, this paper provides an understanding of how natural fibers influence the mechanical properties of concrete. It also proposes a process for the selection and study of any type of natural fiber for further replicability in mix analysis.@en
