Study on the Time-Dependent Characteristics of Sandstone under Chemical Corrosion

Abstract:

The masses, elastic wave velocities of sandstone specimens under chemical corrosion and pH values of solutions soaking specimens are tested in different soak time. It is indicated that elastic wave velocity can be utilized to perform time-dependent test research on the same specimen with the advantage of being highly sensitive to micro void and without damage on specimen in the testing process. The test results show that the relationships between the masses and the chemical solutions are small.The chemical erosion action on rock will reach a relative equilibrium status in a certain time in the closed chemical environment and pH value will reach ultimately one stable value which will be decided by the rock characteristics. The alkalescence of sandstone decides that the solutions of soaking specimen will turn to alkalescence.
