The research carried out focuses on the analysis of the influence of steel fiber and plasticizer additive on the compressive strength of a conventional concrete. The dosages of the steel fiber that was worked on were two, of 20 kg / m3 and 40 kg / m3. For the development of this work, a mix design was developed for the analysis of the design criteria for an effort resistance of 210 kg / cm2, following the methodology of the ACI 211 method. The resistance test was then carried out the compression, thus being able to evaluate and compare the behavior of the different dosages of steel fiber reflected in this investigation. From the results obtained, it was determined that conventional concrete was obtained for a cure age of 7 days; an average compressive strength of 171.40 kg / cm2 for the concrete standard, an average strength of 181.00 kg / cm2 for concrete with the addition of 20 kg / m3 of steel fiber; and an average resistance of 184.10 kg / cm2 for concrete with addition of 40 kg / m3 of steel fiber. For a curing age of 14 days; an average compressive strength of 198.20 kg / cm2 for the concrete standard, an average strength of 210.70 kg / cm2 for concrete with the addition of 20 kg / m3 of steel fiber; and an average strength of 211.60 kg / cm2 for concrete with the addition of 40 kg / m3 of steel fiber. For a cure age of 28 days; an average compressive strength of 220.40 kg / cm2 for the concrete standard, an average strength of 230.60 kg / cm2 for concrete with the addition of 20 kg / m3 of steel fiber; and an average resistance of 238.90 kg / cm2 for concrete with the addition of 40 kg / m3 of steel fiber. Obtaining thus a confidence greater than 95%. It is concluded that an increase in the compressive strength of the concrete was achieved, amounting to 4.63% (CP + 20kg / m3) and 8.39% (CP + 40 kg / m3), consequently expressed a proven recommendation for the increase of the resistance to compression and avoid a concrete with deficiencies in its resistance.
