Análisis experimental de la capacidad filtrante de drenaje de los agregados pétreos provenientes de la Mina Mora, ubicada en la provincia de Tungurahua cantón Ambato

Abstract

The study focuses on determining the permeability of course and fine aggregates, evaluating their potential use for applications in drainage systems. The permeability coefficient of the "Mina Mora" quarry was determined. Three phases were developed to help achieve the main objective of the project. The first phase, called exploratory, consisted of a visit to the quarry to collect essential information such as the georeferencing of the quarry and the obtaining of representative soil samples. In the second phase, the extracted soil was characterized using specific tests: natural moisture content, Atterberg limits, and granulometry. The soil was characterized according to the SUCS classification as a poorly graded sand (SP) and poorly graded sand with the presence of silt (SP-SM), presenting a low moisture content with an average of the samples of 1.98 percent and being a soil with zero plasticity in its majority. Finally, in the third phase, the experimental phase, the aim was to determine the permeability value of each of the samples, dividing them into coarse aggregate, sand, and silt. To find its permeability value, the constant load permeability test was chosen, using the Edibon brand Drainage Permeameter equipment. This equipment allowed us to obtain the permeability coefficient k (cm/s). As a result, it was obtained that the aggregates from the Mina Mora quarry are suitable for use in drainage works.
