Explanatory Video:





Requirements:


  • Take samples of stones weighing at least 25 kg each.


  • Specimen species should be in the form of cubes or cylinders.


  • The lateral dimension or diameter should be of 50 mm at least.


  • The ratio of lateral dimension or ratio of height to diameter should be 1:1.


  • A minimum of three specimens should be used for testing.


Procedure:


  • Specimen is immersed in water at 20 to 30 °C for 72 hours. (Test in saturated condition)


  • Specimen is dried in an oven at 105 ± 5 °C for 24 hours. (Test in dry condition)


  • Then it is cooled in a desiccator to 20 to 30 °C.


  • Later, it is tested in Universal Testing Machine.


  • The load is gradually applied at a rate of 14 N /sq. mm /min (14 newtons per millimetre square per minute) until the specimen breaks down.

here,

Cp= compressive strength of standard specimen piece

b= diameter or lateral dimension

h= height
