Brick Testing helps in
determining the porosity and density of bricks to be used for construction of
load bearing walls. The method involves dimensional measurement and mass to
determine density, followed by measuring the increase in mass when soaked in
water for a standard period.
The amount of water that a brick can
absorb is measured by the water absorption test. There is no distinct
relationship between water absorption and the water-tightness of walls. The
results of water absorption tests are used by the brick manufacturer for
quality assurance.
