Bricks are mainly used in construction of wall, floor, cornices and arches. Brick chips are also used as a substitute of stone chips in concrete mix where stone is not available or an economic solution is prefared. In all the above-mentioned cases, compression load governs. Due to this, compressive strength of bricks is a very important parameter.

e See Section R402.2 for minimum cement content. f For garage floors with a steel trowel finish, reduction of the total air content (% by volume of concrete) to not less than 3% is permitted if the specified compressive strength of the concrete is increased to not less than 4,000 psi. g Compressive strength (f' c) of 2,500 psi, with an approved

bricks. For each proportion 12 number of bricks are casting in that nine bricks are used to determine the compressive strength of brick in N/mm² at 7days,14days,21days curing time and three bricks are used to determine the water absorption. Compressive Stress is determined using Compression Testing Machine (CTM) of 3000 kN capacity.

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.
