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.
