The Peruvian coast is experiencing a significant expansion of urban centers, which in certain areas where harvesting was carried out or there was constant exposure to the Peruvian sea, underwent changes in their composition, specifically the presence of sulfates and other chemical components that directly affect the properties of concrete. In certain cases, different types of cement or additives are required to ensure that the resulting concrete is suitable for the prevailing conditions. The main objective of the presented research is to improve axial compressive strength by using polypropylene fibers for a strength of 280 kg/cm2, with the use of Type V cement. The research incorporates 5% and 10% of the weight of fine aggregate as polypropylene fibers, following the procedure established by the ACI 211 committee for mix design. The research is of an experimental nature and employs quantitative methodology, with direct observation as the technique and laboratory data collection sheets and spreadsheets as instruments. The properties of the aggregates were determined following the Peruvian technical standard, and based on the results, the mix design to be used was determined. The research considered testing at 7, 14, and 28 days, with a total of 27 samples. The results at 28 days showed an average strength of 358 kg/cm2, 308 kg/cm2, and 162 kg/m2 for the mixes with 0%, 5%, and 10% polypropylene fibers, respectively. It was observed that the concrete with polypropylene fibers in these proportions had lower compressive strength compared to the standard concrete mix, decreasing by 13.97% for 5% and 54.79% for 10%. Thus, it can be concluded that the inclusion of 5% and 10% of the weight of fine aggregate as polypropylene fibers does not improve the compressive strength of the concrete. The research rejects the proposed hypothesis and accepts the null hypothesis.
