Water absorption of bricks after 24 hours immersion,
First class bricks : 20%,
Second class bricks : 22 %,
Third class bricks : 25%.

Heavy duty machine made bricks should not absorb more than 5% of their weight.

Garry said: (Jan 7, 2018)

First class brick water% 12 to 15.

Nilesh Pareta said: (Jan 21, 2018)  
15% of its dry weight.
20% of its saturated weight.

Naren said: (Jan 23, 2018)  
Water absorption for 1st class brick is 12 to 15% but in no case exceed 20% so the answer is C.

Narendra Suthar said: (Mar 11, 2019)  
For, 1st class 15%.

Chinnu said: (May 14, 2019)  
Water absorption not exceed 20% by weight and 15% of dry weight.

Chetan said: (Nov 14, 2019)  
As per IS 1077-1973,
For first class bricks, the water absorption capacity should not be more than 20% by weight.

Sushil Rathod said: (Nov 25, 2019)  
After 16 hrs how much 1 class brick absorbed the water by its wt.

Opsc Aee said: (Dec 11, 2019)

1st class brick 15%to20%.
2nd class brick 22%to25%.
3rd class brick 25%to 30%.
IS code standard 1st class brick 20% or 2nd class brick 25% 3rd class brick 30% after 24 immersion cold water water absorption by weight.

Prem Sagar said: (Jun 11, 2020)  
After water absorption 24 hr.
1st class brick 20%.
2n class brick 25%.
3rd class brick 30 more than.

Imran Ahmad said: (Oct 2, 2020)  
The maximum limit for water absorption for first class is 15%.

The second class is 20%.
And the third class is 25%.
According to the new code.
