Properties of First class bricks

Properties of first-class bricks are given below:

Dry first-class bricks should not absorb water more than 20% of their own weight when immersed in water for 24 hours.
No impression should be left on the brick when a scratch is made by finger ail.
They emit a clear ringing sound when two bricks are struck by each other.
First-class bricks are table molded and they are burnt in Kilns.
These are well burnt in kilns.
The surface of the first-class brick should be smooth and rectangular.
The edges of the brick are perpendicular (Make an angle of 90°) to the adjoining edges.
They are regular in shape and size with sharp edges and corners.
They shall be of uniform deep red color.
They should be free from any cracks.
They should be free from chips, efflorescence, flaws, and lumps of any kind.
The average compressive strength of the first-class bricks should not be less than 100 kg/cm2 and not more than 125 kg/cm2.
