    Experiment: __ Date: __/__/20__

    Absorption test on bricks.

    Aim: -

    To determine % water absorption of a brick.

    Apparatus: -Balance, Weights, Water tank, Etc.

    Material: -Bricks, Water.

    Theory: -

    It is necessary to check the % of water absorbed by the bricks beforetaking them for use.

    I.S. Specications: -As per I. !"##$!Water absorption of bricks should not be more than the classified

    specifications. !st'lass Brick ( )"%

    )nd'lass Brick ( ))% *rd'lass Brick ( )&%

    !roce"ure: -!. Take three standard brick specimen, free from impurities and organic

    matter.). Weigh the brick+s by means of balance note down the initial weights

    -W! in the obser/ation table.*. Immerse the bricks in water tank for )0 hours.

    0. The bricks are then taken out and the final weights -W) are noted.
