    Requirements-



    • 150 mm diameter porcelain or glass dish containing 25 mm depth of water is needed for the experiment.



    Procedure-




    • Initially, the ends of the brick are kept in a 150 mm diameter porcelain or glass dish containing 25 mm depth of water at room temperature (20°–30°C).




    • It is kept like this until the entire water is absorbed or evaporated.




    • After that, the water is again filled to 25 mm depth in the dish and the same process is repeated.




    • Finally, the presence of efflorescence is classified as below:




    1. Nil — When the deposit of efflorescence is imperceptible.

    2. Slight — When the deposit of efflorescence does not cover more than 10 per cent of the exposed area of the brick.

    3. Moderate — When the deposit of efflorescence is more than 10 per cent but less than 50% of the exposed area of the brick.

    4. Heavy — When the deposit of efflorescence is more than 50 per cent but the deposits do not powder or flake away from the brick surface.

    5. Serious — When the deposits are heavy and powder or flake away from the brick surface.



    The specifications limit the efflorescence to be not more than moderate (10–50%) up to class 12.5 and not more than slight (< 10 per cent) for higher classes.
