The seemingly most applicable table i could find says "Minimum Compressive Strength" of Clay Masonry Units, depending on the Grade (SW, MW or NW) is, (the lower of the three), 1,250 psi. A foot note states, "Many units have compressive strengths far greater than these required minimum." Conservatively, 0.2f'm = 0.2 x 1,250 = 250 psi.

Explanation: As per IS 3495:1976, Bricks having compressive strength less than 12.5 N/mm 2 should have a moderate rating of efflorescence.. For bricks having compressive strength higher than 12.5 N/mm 2 should not have a rating of efflorescence more than slight.

CSA A288 provides the same result for compressive strength but only for severe and moderate exposure conditions. The crushing strength of the brick to be used in all types of works shall not be less than 7.356MPa unless otherwise specified when tested according to IS:3495 (Part-1).

Compressive strength= Applied Maximum Load X 1000 (N)/ Cross Sectional Area (mm2) (12). The Compressive Strength of fly ash Brick is three times more than the strength of red bricks or clay bricks. Clay bricks minimum compressive strength is 3.5N/mm2 which is much more smaller than the fly ash bricks i.e. 10-12 N/mm2.

What is the compressive strength of bricks? Compressive strength of brick units varied from 4.3 to 6.9 MPa with an average of 5.7 MPa. Average modulus of elasticity was found to be about 3878 MPa., and bricks found to be soft and weak compared to clay bricks.

(i) Kept 5 nos. of brick in water tub for 24 hours, maintain a temperature between 25 0 c to 29 0 c (i.e. 27+-2 0 c). (ii) Take out all bricks after 24 hours. (iii) Kept all bricks stand up vertically at room temperature for drain out the surplus moisture. (iv) Now, prepare mortar at ratio 1:3. (v) Using screen coarse sand of grade 3 mm.

Compressive Strength: Compressive strength of any individual brick shall not be less than the minimum compressive strength for the corresponding class of brick. (See table below) Water Absorption: Shall not be more than 20% by weight up to class 12.5 and 15% by weight for higher classes. Efflorescence

The bricks of high quality should not have strength below 14 N/mm². 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. This test is performed utilizing a compression ...
