For DPC bricks the mean water absorption should be declared by the manufacturer. The mean should not be greater than the declared water absorption and the test involves placing in boiling water for 5 hours. BS 3921 Size of Voids Solid bricks have no perforations or frogs. Perforated bricks have holes not exceeding 25% of the gross volume of brick.
Sound-when one brick is stack by a hammer or other brick the come-out sound should be metallic. Hardness-when scratch with a nail on the bricks there has no impression left on the bricks. Strength-the crushing strength value of the bricks as high as possible. It should not be less than 3.5N/mm2.
The minimum crushing strength of bricks should be 1 Ksi = 1000 Psi = 1000lb/in² OR 7 MPA = 7 N/mm² This is the minimum compressive strength of a brick, though brick strength may vary from location to location and from material to material but these values are the minimum and brick strength should not be less from the above values in any area.
Second-class bricks maintain similar requirements to first-class bricks with specific allowances: Permitted Imperfections: Small cracks and distortions are acceptable within defined limits. Higher Water Absorption: An increased water absorption range of approximately 16–20% of its dry weight is allowed. Minimum Crushing Strength: The minimum required crushing …

Cold crushing strength (CCS) of a refractory brick represents its strength. That is it tells us how much load that refractory can bear in cold conditions. The concept of testing CCS of a refractory material has perhaps, come from metallurgy. This is because for any refractory brick it is rather; rare that it would fail simply due to load on it ...

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.
