GEOTECHNICAL CHARACTERIZATION OF SOME INDIAN ROCKS

Abstract

For the Geotechnical Characterization of rocks the samples from Haryana, Jammu and Delhi region have been collected and Geology and mineral resources of all these places were studied respectively. The minerals occurring in these states are primarily china clay, limestone, dolomite, quartz silica sand, quartzite, slate etc. The samples of different shape and size is prepared as per relevant IS codes and various laboratory test like rebound hammer test, ultra sonic velocity test, point load test, Brazilian test, unconfined compressive strength have been performed on all the rock samples. The study on samples of rock collected indicate that the samples from Faridabad region of Haryana is of marble type, similarly of rock from katra region of Jammu and Kashmir is of sand stone type and samples of rock from Nehru place region of Delhi is of quartzite respectively. The results of these tests were compared with the different models proposed by different researchers. The deviation of the different models from experimental results are calculated and reported in detail in the present work.
