Limits on strength and deformation properties of jointed

1995-01-01· A study of strength and deformation measurements for basaltic rocks, along with consideration of the influence of fracturing using a rock mass classification system, documents the range of brittle response for basaltic rock masses. Although basalts vary widely in composition and other physical factors, many of the properties of a basaltic rock mass appear to vary within a factor of about

Basalt Rock Properties and Uses Science Struck

Rock Hardness. This property is usually measured to find out the compressive fracture strength, to denote whether a rock is softrock or hardrock. The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100-300 Mpa (Megapascal), its tensile strength: 10-30 Mpa, and its shear strength

Compressive strength of rocks PetroWiki

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but many

Estimating uniaxial compressive strength of rocks using

1. Introduction. The determination of basic mechanical properties of rocks is crucial to a specific engineering project. Several mechanical properties, including uniaxial compressive strength (UCS), have become widely accepted parameters for rock design projects (Baskerville, 1987).From past to present, direct and indirect methods have been used to determine UCS of rocks in field and laboratory.

Uniaxial Compressive Strength an overview

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength.
