EFFECT OF ACID-BASE CORROSION ON THE TENSILE STRENGTH OF SHALE UNDER DIFFERENT TEMPERATURE

ABSTRACT
In this study, we mainly investigate the impact of the acid-base corrosion on the tensile strength of the shale under different concentration and water bath temperature of acid-base solutions. Based on the X-ray diffractometry, the SEM and Brazilian splitting tests, the changes of the composition, macro-surface morphology, micro-structure and tensile strength of shale before and after acid-base corrosion are systematically analyzed. The results show that acid-base corrosion would cause chemical damage to shale as a result of the removal of the high hardness minerals and the generation of the dissolved pores and microfractures, resulting in the reduction in its tensile strength. Meanwhile, higher concentration and water bath temperature can promote acid- or alkali-shale interactions and increase the weakening degree of the shale tensile strength.
