The present thesis is entitled "Addition of rice husk ash, to improve the resistance properties of concrete in the San Martin region" was developed at the Civil Engineering and Architecture Faculty of the National University of San Martin - Tarapoto. The research was experimental, and its main objective was to add rice husk ash to improve the resistance properties of concrete. The materials used were: Pacasmayo type I cement, coarse and fine aggregates, potable water and rice husk ash. In the investigation it was designed f'c=175 kg/cm2 and 210 kg/cm2, preliminary specimens were elaborated with six percentages of addition, three percentages of work were defined: 2%, 4% and 6%, tested to the compression effort of concrete. Finally, it was determined that the adequate percentage of addition is 2%, with which the bending stress of concrete was tested. The results after 28 days are mentioned below: For the first standard design, the resistances were f'c=176.53 kg/cm2, Mr= 39.34 kg/cm2, and with an adequate addition of 2%, f'c (2%)=177.66 kg/cm2, Mr (2%)= 41.57 kg/cm2 were obtained; for the second standard design, the resistances were f'c=210.35 kg/cm2, Mr= 46. 06 kg/cm2, and with an appropriate addition of 2%, f'c (2%)=213.82 kg/cm2, Mr (2%)= 47.83 kg/cm2 were obtained, concluding that, the percentage of addition of 2%, slightly improved the resistance to compression by 0.64% and 1.65%, for both designs, and the resistance to bending improved by 5.67% and 3.84%, respectively.
