| Abstract: | An extensive attention has been paid to the effect of chemical solution on rock properties. The physical and mechanical characteristics of calcareous cementitious feldspathic sandstone specimens subjected to hydrochloric acid attack were investigated by means of the accelerated corroded test. The progressive and deteriorative mechanism of the specimens in different acid solutions is revealed. The results indicate the acid environment has strong influence on rock mechanical properties. |
