The strength of a single brick masonry unit varies widely, depending on its ingredients and manu- facturing method. Brick can have an ultimate compressive strength as low as 1,600 psi. On the other hand, some well-burned brick has compressive strength exceeding 15,000 psi. Because portland-cement-lime mortar is normally stronger than the brick

The determination of cold crushing strength (CCS) is also highly important in case of refractory insulating bricks where bricks have to be porous as well as strong. For the measurement of the CCS, according to EN 993-5, a steadily increasing compressive load is applied to the refractory test piece by a compressive machine until the test piece fails.

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 BIS: 1077-1957, the minimum crushing or compressive strength of bricks is 3.50 N/mm2. The bricks with crushing strength of 7 to 14 N/mm2 are graded as A and those having above 14 N/mm2 are graded. as AA.

Bricks that are used for masonry construction are generally subjected to compressive loads thus it is necessary to determine the compressive strength of bricks. The compressive strength test is also known as the crushing strength test which is an important type of laboratory test conducted on bricks to determine the load-carrying capacity of bricks when subjected to a compressive load.

The crushing strength of the bricks is determined by placing the bricks in a compression testing machine. After placing the brick in a compression test machine, apply the load on it until the brick is broken. Note the value of the failure load and find the crushing strength of the brick. The minimum crushing strength of brick is 3.50 N/ m ㎡.
Compressive Strength Test of Bricks. The determination of Compressive Strength Test of Brick is carried out under the specification of ASTM C67-03. Sampling of Brick. Selection of Test Specimen: Full-size representative bricks should be sampled randomly to cover the whole range color, texture, and sizes from a shipment.

The average crushing strength and tensile strength of hand moulded bricks are 60,000 kN/m 2 and 2000 kN/m 2 respectively. The shearing strength of bricks is about one-tenth of the crushing strength. In practice, however, the bricks are not subjected to the tensile stresses.
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.

Cold Crushing Strength (CCS) of Refractory Bricks and Castables. 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
