Quantity Take Off or QTO is a well known project estimating company serving to the contractors, home builders, architects, design- build firms and sub contractor trade. We are providing estimating service since 2002 with a great chronicle of success.
This construction video tutorial is made on the topic of water
absorption test in brick.
video starts with selecting some bricks out of a series of bricks and keep them
aside. Mark them with the numbers 1,2 and 3. These bricks have to undergo a hot
pack process by immersing them into a bucket filled with hot water at the room
temperature of 280C. Pour more water to maintain the adequate level of the
water. Keep this suturing method continued for 24 hours.
After the completion of 24 hours the bricks are taken out
from the water tank one by one. After that, with the use of a cotton cloth, the
bricks are wiped off and cleaned. Now take the weights of these bricks and
denote them with W2 i.e. weight of the bricks in saturated conditions. The
weight is taken through a digital weighing machine. All the values of weight
are recorded in a paper.
Now the bricks are transferred to a hot air oven for water
hydration test at 1050C and keep them for 24 hours.
completion of 24 hours, turn of the power of the oven and take out the bricks
and put them in a tray. Now, again take the weight of the bricks through the
digital weighing machine and denote them with W1 i.e. weight of the brick in
dry condition. All the values are recorded in a paper.
The weight of
brick in dry condition (W1) in Kg is given as follow :- Specimen 1 = 2.896, Specimen 2 = 2.945, Specimen 3 = 2.902
Brick in Saturated Condition (W2) in Kg is given as follow :-
Specimen 1 = 3.025, Specimen 2 = 2.987, Specimen 3 = 2.980
In order to find out the percentage of water, apply the following
W2 – W1/W1 x 100
