The present investigation was carried out in the district of San Hilarion, region of San Martín, whose objective was to determine the compressive strength of plain concrete by adding rice husk. The thesis is of an applied type and a descriptive level, the study variable was the rice husk and we considered plain concrete as a population with a resistance of 210 kg/cm2 and as a study sample, cylindrical concrete specimens with 3 different dosages of addition of rice husk, which were 2%, 4% and 6% respectively. For data collection we rely on techniques such as observation, laboratory tests and documentary analysis. Likewise, for data tabulation we rely on Microsoft Office Excel. In this way, it was possible to obtain an average compressive strength of 212.13 kg/cm2 for the standard concrete, representing 101% of the design strength, which was only exceeded by the 2% addition that obtained 252.97 kg/cm2., representing 120% of the design resistance. For the percentages of 4% and 6%, 184.73 kg/cm2 and 183.23 kg/cm2 were obtained, representing 88% and 87.3%, respectively, of the design resistance, remaining below the standard concrete. In this way, a decreasing trend is deduced by adding more rice husks. Likewise, it is emphasized that the optimal percentage of addition was 2% of rice husk in replacement of fine aggregate in a conventional concrete mixture, since it managed to obtain an additional 20% of the design resistance. Which would mean a positive impact for the environment and costs of a project.
