Water Absorption Test of Bricks (IS: 3495 (Part II))

Water Absorption Test of Bricks

The Water Absorption Test of Bricks can be classified into two tests:-

24 Hours Immersion Cold Water Test:-

Requirements:-

• Dry bricks, oven and a damp cloth.

Procedure:-

• Dry bricks are put in an oven at a temperature of 105 ° to 115°C  till these bricks attain constant mass.

• The weight (W1) of the bricks is recorded after cooling them to room temperature.

• The bricks are then immersed in water at a temperature of  27° ± 2°C for 24 hours.

• The specimens are then taken out of the water and wiped with a damp cloth.

• Three minutes later, it is weighed again and recorded as W2.

• Now, the Water Absorption in percentage is:-

Water Absorption in % 

Five Hours Boiling Water Test:-

Requirements:-

• Dry bricks, oven and a damp cloth.

Procedure:-

• The weight of oven-dried bricks (W1) is recorded in the same way as in the test above.

• Then the specimen is immersed in the water and boiled for 5 hours.

• It is followed by cooling down to 27° ± 2°C by a natural loss of heat within 16-19 hours.

• The specimen is taken out of the water and wiped with a damp cloth and weight is recorded as W2.

• Now, the Water Absorption in percentage is:-

Water Absorption in %

Note:- The average water absorption shall not be more than 20% by weight up to class 12.5 and 15% by weight for higher classes.
