Answer / jai.vignesh

first class bricks = Between 7 to 10 N/mm2
Second class bricks= Between 3 to 7 N/mm2
Third class bricks = Less than 3 N/mm2 (should not used)

Answer / karthik

For First class bricks - Compressive strength Should not be
less than 14 N/mm2

and for Second class Bricks - Should be under 7-14N/mm2

The minimum compressive strength of concrete should not be
less than 3.5N/mm2.

Note : If any brick which has a compressive strength of less
than 3.5N/mm2 should be rejected..!!
