Water Absorption Test

A standard soaking-in-water test can determine the porosity of bricks, which can then be used as an indication of the potential for the development of problems related to the penetration of salts and other materials into the units, such as salt attack and efflorescence.

The bricks, when tested in accordance with the procedure laid down in IS 3495 (Part 2) : 1992 after immersion in cold water for 24 hours, water absorption shall not be more than 20 % by weight up to class 12.5 and 15 % by weight for higher classes.
