An experimental study of the disintegration characteristics of red clay

In order to study the disintegration characteristics of red clay, red clay from Guilin is prepared into different water content samples, and the red clay is disintegrated by the homemade test equipment. Considering the effect of red clay on water absorption, a parallel water absorption test is carried out for each disintegration test. The disintegration-time curve is corrected with the results of the water absorption test, and a new dissolution calculation formula is proposed. In this experiment, the disintegration characteristics of red clay at different water content and temperatures are investigated. The results show that the amount of disintegration decreases with the increasing water content, and the water content is more than 25%. The red clay does not decompose in 2 h; the amount of disintegration increases with the increasing temperature, but in the natural environment, the disintegration of clay is not sensitive to temperature. The comprehensive analysis of moisture content and temperature shows that the moisture content is the main influencing factor for soil disintegration in the natural climate range.
