Fractal Evolution Law of Clay Rock Disintegration Under Different pH Conditions

Abstract:

Based on the similarity principle and the conservation of mass, the microscopic fraction disintegration and macro distribution of rock particles are discussed separately, and the correlation fractal dimension calculation formula about rock disintegration is also presented. On this basis, the fractal evolution law of clay rock disintegration under different pH conditions is investigated. The results show that, the smaller the pH value, the greater the fractal dimensions in the preliminary stage and the fewer the cycle times to obtain the stable fractal dimension. In addition, the acid solution accelerates the growth of particle fractal dimension, but the alkaline solution plays a role of reverse. It needs more cycle times that the fractal dimension curves become stable in the alkaline conditions. However, the fractal dimension under different pH conditions should tend to be equal ultimately.
