Análisis comparativo entre la humedad gravimétrica y la humedad determinada con sensores electrónicos en suelos finos del cantón Pastaza. provincia de Pastaza

Abstract

Due to the fact that it is vitally important to determine the gravimetric moisture content within Civil Engineering applied to concrete, resistance of the subgrade layer on roads, determination of foundations, implementation of piles, etc.; proceed with this comparative analysis. For the beginning of this investigation, different samples of fine soils extracted from the Pastaza canton were obtained, different laboratory tests governed by regulations were applied (moisture content, granulometry, Atteberg limits, modified Proctor type B), and analyzed. data provided by electronic sensors (capacitive and resistive) that determine the natural moisture content of the soil, for subsequent correlation and interpretation of how effective and reliable these sensors are. Through the comparison made from 15 samples between the gravimetric humidity and the humidity determined with electronic sensors, it was possible to determine that the resistive sensor provides an excellent correlation coefficient, with a value of 94 percent, for a working range of 566.50 to 924.33, while the capacitive sensor provides a good correlation coefficient, with a value of 70 percent for a working range of 339.67 to 532.33 in its field readings.
