The purpose of this work is to analyze in a comparative way the resistance to bending and compression between traditional concrete and concrete with added sawdust at 5%, 10% and 15% according to the ACI 211 standard, as well as the comparison in production cost. For the methodology, since it is a pseudo-experimental investigation, the population is the same as the sample, 60 cylindrical specimens and 66 prismatic specimens, of which 24 cylindrical specimens plus 30 prismatic beams were designed with conventional concrete and 36 more cylindrical specimens. The remaining 36 prismatic beams were designed with conventional concrete adding recycled steel fibers with 4 mm, 3/8” and ½” steel reinforcements, the aforementioned is tested at: 7 days, 14 days, and 28 days after the date of casting, 5%, 10% and 15% with added recycled steel fiber. The results of the laboratory showed a significant increase in the resistance to compression (specimen) and bending (beam reinforced with 3/8 ”reinforcing steel) when adding 5% of recycled steel fiber to the conventional mixture, likewise, there is no a significant increase in the same by adding 10% and 15% respectively, to corroborate the aforementioned, the ANOVA test was carried out in the statistical program IBM SPSS V.25, likewise, there is a saving compared to the traditional one of almost 15% . With the results, it was concluded that the best option is concrete with added 5% of recycled steel fiber and reinforced with 3/8” steel, both technically and economically.
