The mix design has been done as per IS:10262. Advantages of mix design Mix design Properties of Bricks Compressive Strength Hardness,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.
