  • 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 abovementioned cases, compression load governs. Due to this, compressive strength of bricks is a very important parameter.
