Modern bricks are made by more controlled

For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S (from an f’ m of 1750 psi to 2000 psi for CMU units with 2000 psi compressive strength). The compressive strength of the masonry units is the largest factor, by far, in masonry assembly compressive strength.

The minimum crushing strength of second class brick should be 70 kg per sq cm. Specification of Third Class Bricks. These bricks are slightly under burnt or over burnt. They are not uniform in shape, size and edges. They shall not observe water more than 25% of their own dry weight after 24 hours, immersion in cold water.

The crushing strength of a brick is found out by placing it in a compression testing machine. It is pressed till it breaks. As per BIS: 1077-1957, the minimum crushing or compressive strength of bricks is 3.50 N/mm2.
