10 Test On Building Stone: Stone Test names, Tensile strength

Crushing Test On Building Stone Durability test test that is carried out is alternate wetting and drying test. To quicken the effect in alternative wetting and drying test, a saturated solution of sodium sulphate or magnesium sulphate is used instead of water, freezing and thawing test.

COMPARING LABORATORY AND FIELD DURABILITY TESTING …

test device – the Rockland 5804A Analyzer as manufactured by Rockland Scientific Corporation – is used by WJE to monitor and record the frequency of the vibration. This test device is not the same as that noted in ASTM C215, but it provides identical test results. Depending on the durability of the stone tested, a change in frequency

Engineering Properties of Stones and Tests on Stones ...

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

For conducting this test, a specimen of size 40 × 40 × 40 mm is prepared from parent stone. Afterward, the sides are finely dressed and placed in water for three days. The saturated specimen is provided with a layer of plaster of paris on its top also bottom surfaces to get even surface so that load applied is distributed uniformly.

or THE RELATIVE DURABILITY OF ILLINOIS BUILDING STONE,

The compression test is included in the artificial methods of testing durability, because a stone that is strong is usually also durable; but the test is not of very great importance. The freezing test is the most important of all of the artificial meth­ ods. The chief cause of …
