Análisis de la influencia de la ceniza de cascarilla de arroz en los parámetros de resistencia al corte de suelos arcillosos compactados de la Sierra y el Oriente

Abstract

The purpose of this academic article is to analyze the influence of rice husk ash on the shear strength parameters of clayey soils from the Highland and Amazonic Regions compacted with this material. For its analysis, laboratory tests were carried out to determine: fundamental relationships, SUCS classification, optimal moisture content and maximum dry density for the soil without RHA and improved with different percentages of RHA. In addition, direct shear tests were carried out in order to determine the angle of internal friction and cohesion. On the other hand, a comparison was made between samples with and without ash, the loading conditions were similar, in order to assess the variation in these shear parameters. Finally, the effects of the mixture of clay with RHA on the shear strength parameters of the compacted soil were analyzed and validated, evidencing the variation in the behavior of the material obtained from samples of each region.
