    Five Hours Boiling Water Test:-



    Requirements:-



    • Dry bricks, oven and a damp cloth.

    Procedure:-



    • The weight of oven-dried bricks (W1) is recorded in the same way as in the test above.


    • Then the specimen is immersed in the water and boiled for 5 hours.


    • It is followed by cooling down to 27° ± 2°C by a natural loss of heat within 16-19 hours.


    • The specimen is taken out of the water and wiped with a damp cloth and weight is recorded as W2.


    • Now, the Water Absorption in percentage is:-
