This test helps in determining the porosity and density of bricks to be used for the construction of load-bearing walls. The method involves measurement of dimensions and mass to determine density, followed by measuring the increase in mass when soaked in water for a standard period of time.
Test Method: IS: 1528 (P-8,9)1974
In this test, we assess 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.
Test Method: IS: 3495 (P-2)1992
This test helps in determining the permanent linear change of refractory brick when heated under prescribed conditions, which will measure any potential shrinking when used for load-bearing walls.
Test Method: IS: 1528 (P-6)1974
The abrasion resistance of a refractory material provides an indication of its suitability for service in abrasion or erosive environments.
Test Method:IS: 5688-1982
Creep in compression (CIC) refers to the percentage of shrinkage of a refractory test piece under a constant load and exposed to a constant high temperature over a long period of time.
Test Method: IS: 1528 (P-18) 1993
The modulus of rupture (MOR) is the maximum surface stress in a bent beam at the instance of failure. One might expect this to be exactly the same as the strength measured in tension, but it is always larger because the volume subjected to this maximum stress is small, and the probability of a large flaw lying in the highly stressed region is also small.

This test helps in determining the strength of fly ash/lime bricks.
