Abstract :Many methods of determining the abrasiveness of rocks were developed  by a number of researchers. Although the effect of liquids on the mechanical properties  of rocks has been investigated by some authors, the effect of liquids on the abrasivity of  rocks has not been published. In this paper, the effect of different liquids on the  abrasivity and mechanical strength of rocks was investigated. To achieve this goal;  samples of sandstone, limestone and tuff were tested under laboratory conditions. The  liquids having 4, 7.5 and 10-pH degrees were used in the experiments, representing  acidic, alkaline and neutral conditions respectively. It was observed that the liquid  which has a pH degree of 4 significantly increased the abrasivity of the above  mentioned rocks. Compared with their dry values, the point load strength of the rock  samples decreased when saturated with different liquids.
