Introduction Uniaxial compressive strength (UCS) is one of the most widely used rock mechanical parameters in rock engineering like design and construction of foundations, tunneling, slope stability investigations, etc. UCS is also the only parameter to assess rock material strength in Rock Mass Rating (RMR) proposed by Bieniawski (1989).
Uniaxial compressive strength tests were performed according to standard test EN 1926 (2007) using an Ibertest MEH2000H/FIB50 servocontrolled hydraulic testing frame. Six samples of each lithotype were tested. Uniaxial compression test was performed at a constant displacement rate of 4 mm/h.
Uniaxial compressive strength of the travertine in the study area ranges from 30 to 80 MPa. Besides that, Black colored dolomite rocks occupies in Bozkurt that is one of the county of Denizli. Strength of the dolomite varies from 80100 MPa.
The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heattreated 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. Some results for uniaxial compressive strength σ c and tensile strength σ t ...
In this study, 31 empirical equations are summarized that relate unconfined compressive strength and internal friction angle of sedimentary rocks (sandstone, shale, and limestone and dolomite) to physical properties (such as velocity, modulus, and porosity).

The investigation performed on dolomite samples shows that for the uniaxial and conventional triaxial compression tests, the above mentioned methods give quite similar values, except for the crack volume strain method. Crack initiation threshold determined by this method has a distinctively lower value than that obtained by the other methods.
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.
The uniaxial compressive strength (UCS) is the maximum axial compressive stress that a rightcylindrical sample of material can withstand before failing. It is also known as the unconfined compressive strength of a material because confining stress is set to zero.
Mar 31, 2019· Compressive strength is important as it is the main criteria used to determine whether a given concrete mixture will meet the needs of a specific job. Concrete psi. Pounds per square inch (psi) measures the compressive strength of concrete. A higher psi means a given concrete mixture is stronger, so it is usually more expensive.
Abstract. The ratios M R = E/ σ c for 11 heterogeneous carbonate (dolomites, limestones and chalks) rock formations collected from different regions of Israel were examined. Sixtyeight uniaxial compressive tests were conducted on weaktostrong (5 MPa < σ c < 100 MPa) and very strong ( σ c > 100 MPa) rock samples exhibiting wide ranges of elastic modulus ( E = MPa), uniaxial ...
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive ...
