Abstract
Many attempts have been made to determine the uniaxial compressive strength and elastic modulus of regular specimens of rock indirectly. But little experimental work has been done to find above two parameters using Brazilian test value up to date. This paper employs Brazilian test value to estimate uniaxial compressive strength and elastic modulus of sedimentary (sand stone, shale) and metamorphic (gneiss) rocks. High reliability of Brazilian test has been supported by the established conclusions drawn from point load test and Schmidt hammer strike values. It has also been found that this method can be applied easily and rapidly to the estimation of uniaxial compressive strength and elastic modulus of rock cores when direct tests are not available.
