What is the minimum compressive strength of a brick according to IS codes ?

  • Compressive strength test on bricks are meted out to see the load carrying capability of bricks under compression. This test is meted out with the assistance of compression testing machine.
  • Bricks are usually used for construction of load bearing masonry walls, columns and footings. These load bearing masonry structures experiences largely the compressive loads. Thus, it's necessary to understand the compressive strength of bricks to envision for its suitableness for construction.
  • Apparatus, sampling, procedure and calculations to see the compressive strength of bricks are mentioned below.
  • Minimum compressive strength of brick varies for different grades of bricks
    • For Common building brick = 35kg/sq. cm
    • For second class brick = 70kg/sq. cm
    • For First class brick = 105kg/sq. cm
    • For AA class brick = not less than 140kg/sq. cm
