In rock strata, there are numbers of hair cracks and fissures are present. It degrades the physical and engineering properties of rock. Hence, problem occurs while excavation during tunneling and mining operations. Jointed rock masses comprise interlocking angular particles or blocks of hard brittle material separated by discontinuity surfaces which may not be jointed with weaker materials. Three types of carbonate sedimentary rock viz. Limestone, building stone and Marl procured from Porbandar,Gujarat (India). Samples are having different amount of calcite mineral. Chemical analysis is being done in order to get the exact amount of mineral present. its mineral effect is also be taken care. Matrix. The main Objective is to compare the strength of intact rock with their proposed rock matrix pattern and variation due to decrease in amount of calcium carbonate. secondary to know the behavior of rock specimens under confining pressure & plot stress vs. strain curve for the same.
