2019.1.12 Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of 5.5 N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 3.5 N/mm 2 it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.

2023.3.6 Compressive resistance of bricks. First-class brick has a compressive strength of 105 kg/cm². The compressive strength of a second-rate brick is 70 kg/cm². Common building bricks have a compressive strength of 35 kg/cm². The compressive strength of sun-dried brick is between 15 and 25 kg/cm².

It is thus obvious that not only the bricks of different brick fields will have different strengths, but in the same brick field, the bricks of the same batch may have different strengths. The average crushing strength and tensile strength of hand moulded bricks are 60,000 kN/m 2 and 2000 kN/m 2 respectively.

This is arguably the most crucial property of brick, particularly if they are being used for load-bearing walls. Clay bricks should have a minimum compressive strength of 9N/mm² for a building up to two storeys high, and 13N/mm² for anything higher. Bear in mind that if the crushing strength of a brick is below 3.5N/mm², it should not be used.

(2) Crashing Strength: The crushing strength of a brick is found out by placing it in a compression testing machine. It is pressed till it breaks. As per IS: 1077-1970, the minimum crushing or compressive strength of bricks is 3.50 N/mm 2. The bricks with crushing strength of 7 to 14 N/mm 2 are graded as A and those having above 14 N/mm 2 are ...

compression test-on the other hand, brickwork strength may greatly exceed the cube crushing strength of the mortar used in it. Finally, it has been shown that the compressive strength ofbrickwork varies, roughly, as the square root of the nominal brick crushing strength, and as the third or fourth root of the mortar cube strength.

3-Nov-2009. 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 ...
