As a result of crushing, the maximum boulder impact force and maximum transmitted loads for flaky rocks are about 20% and 33%, respectively, smaller compared to that for bulky rocks.Properties of Rocks | Geology,Two rocks of the same type with the same resistance to crushing can offer different resistances to attrition. The resistance of a rock to fracture is approximately 1/10 to 1/30 of the ultimate resistance to crushing. Some physical and mechanical properties of rocks, important in technology are given in table-7.
