The relations between many kinds of physical and mechanical properties of rocks, such as density, water absorption, compressive strength, tensile strength, shear strength and Young's Modulus were investigated using many test data in author's laboratory. Each relation between particular two properties as listed above, has wide variety according to the kind of rocks. So, it is difficult to establish simple relation through all kinds of rocks. The properties of particular kind of rocks, such as granite, andesite, tuff, sandstone and mudstone, have fairly good relations with each other properties, so, these relations on main kinds of rocks were illustrated systematically in figure-20, with common parameter of uniaxial compressive strength (in dry condition). Using these relation, a kind of physical property may be estimated from other properties Through above investigations, and other information on weathring test and ultrasonic velocity measurement of rocks, anther proposed an attempt to classify rocks with these physical properties. The compressive strength is selected to be common index of classification. Most of other physical properties seems to show some remarkable change at 1500 kg/cm^2 and 300 kg/cm^2 of compressive strength, so these values may be useful to classify rocks, such as compressive strength>1500 kg/cm^2…Very hard〜Hard Rocks compressive strength=300〜1500 kg/cm^2…Moderately hard〜Moderately soft Rocks compressive strength<300 kg/cm^2…Soft〜Very soft Rocks.
