Compressive Strength of Brick Civil Engineering

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.
