BORDERS AND METHOD FOR DETERMINING THE NUMBER OF PLASTICITY CLAY SOILS by infrared spectroscopy

摘要

A method for determining the boundaries and the number of plasticity of clay soils comprising preparing soil samples with different water content, characterized in that the measured infrared spectra of each sample, which emit the characteristic frequency of the crystal lattice clay minerals, each of which build a graph of intensity, frequency, or energy of water content, wherein an amount of water corresponding to the transition soil in plastic state is judged by two characteristic kink in poluch ennoy curve, wherein the first primer corresponds to kink at the boundary rolling humidity (W), the second - the soil moisture at the boundary flow (W), and plasticity (I) corresponds to the interval between two moisture characteristic curve break points to determined.
