Various properties of bricks as detailed in the previous article are tested and evaluated according to a set of practice.. These tests ( compressive strength of bricks, absorption, efflorescence & size) have been described in detail in relevant codes prepared and published by Bureau of Indian Standards.
Bricks are mainly used in construction of wall, floor, cornices and arches. Brick chips are also used as a substitute of stone chips in concrete mix where stone is not available or an economic solution is prefared. In all the above-mentioned cases, compression load governs. Due to this, compressive strength of bricks is a very important parameter.
Under pressure. To work out how high a tower can be before it crushes itself, you need to know two things: the mass of material, and its yield strength.
