Research on Similar Material in Physical Specimen Petrography of Rock
The similar material composed of quartz sand, gypsum, colophony and alcohol solution, model test and similarity theory were depended on in the test, and standard cylinder specimens were made in different proportions. The physical and mechanical properties of blocks were studied through uniaxial compressive experiments. The researches show that the ratio of elastic modulus and down modulus of the specimens increase linearly with the increase of the ratio of sand and cement; while the elastic modulus, the down modulus and the uniaxial compressive strength decrease in shah model of index function with the increase of it. All parameters mentioned above reduce rapidly with the increase of the ratio of sand and cement when the ratio of sand and cement less than 4, if not, the parameters increase slowly.
