Experimental Studies on Disintegration Features of Carbon Mudstone

Abstract:

Carbon Mudstone will have a complicated change in the aspect of physics, chemistry and mechanics behavior when wet. Thus, it is difficult to describe the process in a quantitative standard. In order to find out the effect of testing conditions and water content, there are two different conditions in test drying and original state samples, one is outdoor test and the other is indoor soaking test. What’s more, Fractal Theory is used in the research of Carbon Mudstone. The result shows: A short-lived process of water absorption and weight increment appears in the initial disintegration; Different conditions will result in different destructional forms of samples; The key reason of disintegration is that wetting and drying cycle results in the change of water content; The difference of water content partly affects the process before disintegration, but less affects fractal dimension after disintegration.
