· Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than N/mm 2 it must not be used. A field test about strength of the bricks is to fall the from a height of 1 meter and it must not break in to pieces.

Sandlime hollow bricks are made of lime and sand as the main raw materials. The hollow with a hole rate less than 15% is made by the preparation and pressing of blanks and autoclaved curing. According to the compressive strength, the limesand hollow can be divided into five strength grades: MU25, MU20, MU15, MU10 and

Bricks are mainly used in construction of wall, floor, cornices and arches. 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.
