  • 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

What is the maximum strength of cub compress strength in one cub testing ?

  • First of all, we make the concrete cube at some mix proposition as M15, M20.
  • Then after one day the curing on concrete cube at 7days or 28days and we find out the compressive strength of concrete

Sampling of Cubes for Test :

  • Clean the mounds and apply oil.
  • Fill the concrete in the molds in layers approximately 5cm thick.
  • Compact each layer with not less than 35strokes per layer using a tamping rod (steel bar 16mm diameter and 60cm long, bullet pointed at lower end).
  • Level the top surface and smoothen it with a trowel.
