Abstract

In certain engineering tasks of preliminary nature there is a need for an estimation of important physical and mechanical properties such as uniaxial compressive and tensile strength. This paper analyzes the problems related to the assessment of uniaxial compressive and tensile strength of rock material in the deposit of gypsum in the Knin area. Its engineering characteristics strongly depend on the quantity of ground water and temperature and therefore it is difficult to conduct laboratory tests on this kind of material. The paper describes the comparison of estimates using equations published in the literature and equations that have been established on the basis of the research for the purpose of writing this paper.
