    Análisis comparativo entre los valores del límite líquido obtenidos por copa de casagrande y penetrómetro de cono para suelos granulares del cantón Ambato, provincia de Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2021-03) Ramírez Maiquiza, Silvia Maribel; Pérez Maldonado, Ruth Lorena
    Currently, in the soil mechanics laboratories of Ecuador, the Casagrande cup method is the best known to determine the liquid limit of the soils standardized by ASTM D4318, while some countries use the Cone Penetrometer established by British Standard BS 1377-2:1990. A comparative analysis was carried out between these methods and not having this equipment to perform the tests in the laboratory, was designed and assembled at the INDUACCS company in Ambato, according to the specifications of BS 1377-2:1990 standard, then test trials were conducted that provided adequate results. For the tests, soil samples were taken in the 18 parishes of Ambato canton, obtaining a total of 30 specimens, which were used for laboratory tests; with the results was made a comparative statistical analysis between the values of the liquid limit obtained by testing the Casagrande cup and the Cone Penetrometer, for this analysis was applied the statistical method of minimum squares. Based on the results and analysis, it demonstrated that the alternative method using the Cone Penetrometer built in this research, is acceptable to obtain liquid limit values of granular soils, it is also important to mention that the methods have a strong positive correlation (r = 0.8228).
