The physico-mechanical properties of rocks are important parameters in the planning and design of mining and civil constructional works. These properties are adversely affected by acidic and alkaline environments. In the present study, marble rock specimens were tested in the laboratory after treatment with different pH solutions for 15 h. The physico-mechanical properties of the marble were determined in both acidic and alkaline conditions. The study revealed that the strength properties are higher at pH 7 and lower in acidic and alkaline conditions. The strength reduction in acidic conditions is greater than that in the alkaline conditions.
