Experimental Study on the Mechanical Properties of Sandstone under the Action of Chemical Erosion and Freeze-Thaw Cycles

<div>Stress-strain relationship for uniaxial compression tests after different chemical solution eroded and different number of freeze-thaw cycles (F-Tc): (a) uniaxial stress-strain curve under the acidic solution, pH = 3; (b) uniaxial stress-strain curve under the neutral solution, pH = 7; (c) uniaxial stress-strain curve under the alkaline solution, pH = 13.</div>
