Experiment Study on the Effects of the Dehydration Methods on the Micropore Structure Characteristics of Bentonite

Abstract:

As a natural nanomaterial, the bentonite is widely used in industry and engineering, and it is used in the anti-seepage (infiltration) project in civil engineer because of its low permeability. The micro-pore structure characteristics of the bentonite with the different dehydration methods are measured by Mercury Intrusion Porosimetry (MIP) in this text. Then the effects of the dehydration methods on the micro-pore structure characteristics of bentonite are analysed and the detailed reasons of the test errors are given. The results of the research have certain referential value for the application of the bentonite in civil engineering and play a guiding role on how to reduce the errors and to improve the authenticity and the reliability of the test.
