Researching Characterization of Adsorbed Water Parameters Based on Macro - Mechanics Index

Abstract

The adsorbed water formed on clay minerals particle surface is an important microscopic physical factor that remarkably influences the physical condition, the strength and deformation of engineering characteristics of clay. Quantitative description of the relevant parameters associated with adsorbed water has an important theoretical significance. Clay can present different physical states, by analyzing the relationship between the adsorbed water content and different physical states, the connection between the adsorbed water mass and Atterberg limits was built, and the relevant expression was derived. On this basis, assumed that the clay particles are platy, then, the formula of the adsorbed water thickness was deduced. A new way to quantify the microscopic parameters using macroscopic physical mechanics index was opened up.
