THE INFLUENCE OF SATURATION ON THE UNIAXIAL COMPRESSIVE STRENGTH OF LIMESTONE IN EXPLORATION AREA CRNOGLAV NEAR NEUM

Abstract

Exploration area Crnoglav, near Neum, Bosnia and Herzegovina, is composed of limestone sedimentary rock. Research of influence of saturation with water was made on intact material from this area on physical and mechanical properties of the rock: uniaxial compressive strength, module of deformation, point load strength index and Schmidt rebound hardness. Tests were conducted on recommendation of International Society for Rock Mechanics (ISRM Suggested methods) and Croatian Standards. Results showed different influence of saturation on values of respective test. Ratios that help with calculations of physical and mechanical properties of rock in their saturated state based on their known values in dry state are presented in this paper (the paper is published in Croatian).
