Unconfined Compressive Strength Test Procedure Check the ability of the spherical seat to rotate freely in its socket before each test. Place the lower platen on the base or actuator rod of the loading device. Wipe clean the bearing faces of the upper and lower platens and of the test specimen, and place the test specimen on the lower platen.

Abstract Mining rock salt results in subsurface damage, which may affect the strength because of applied stress, anisotropy, and deformation rate. In this study, we used a Kolsky compression bar to measure the high strain rate response of bedded and domal salt at strain rates up to approximately 50 s−1 in parallel and perpendicular directions to bedding or foliation direction depending on ...

salt rock is an important issue. At present, there are three main methods for determin- ing the long-term strength of rock: The first method is to determine the corresponding crack damage stress when the rock sample volume strain begins to reverse as the long- term strength of the rock,7but the method does not apply to salt rock.

As a special soft rock, rock salt can exhibit a large deformation under triaxial stress conditions.In this paper, the author presents triaxial compressive tests which were carried out under different confining pressures on rock salt samples taken from Anning natural gas storage cavern, located in Yunnan Province, China. The axial stress of rock salt was analyzed by four methods based on ...

In a study by Zaimoğlu et al. (2019), rock salt decreased the 28-day unconfined compressive strength of grouts. These findings are similar to the result of the study. Rock salt causes salt crystallization with physical erosion in concrete (Zhou et al., 2021). And the salt crystallization reduces the strength.

The mechanical properties of gas-containing coal and rock mass play important roles in controlling the occurrence and development of coal and gas outbursts. The gradual increase in mining depth will change the failure mechanism of gas-containing coal and rock mass. In order to further study the failure mechanism of gas-containing coal and rock mass, samples were taken from the gas-containing ...

Answer (1 of 7): Compressive strength of rock denotes the maximum stress that can be applied on the given rock for a unit area. Safe bearing capacity is a fraction of the ultimate bearing capacity usually one third. A rock strata generally not uniform. Fissures and faults are plenty. The strata...

Gastaldini et al. (2015) has shown that by partial substitution (0%-30%) of ASA for cement, the compressive strength at both 7 days and 28 days of curing increased for all specimens, except for 5% replacement at 7 days. The maximum strength was achieved for samples with 25% ASA replacement at 28 days.

Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.

Through analyzing the salt rock deformation under triaxial compressive stress condition, the large compressive deformation properties of salt rock under higher confining pressure are shown. The problems of the axial stress-strain obtained by axial load divided by the initial cross-sectional area of the specimen are pointed out for triaxial compressive tests. Thus the engineering strain and ...
