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.
