Difference between clay bricks and cement/concrete bricks with refernce to manufacturing and use on site?

Answer 1

i believe clay bricks can handle higher temperatures

Answer 2

Clay bricks have to be fired in a kiln in order to harden them. Cement / concrete bricks have to cure and that takes time.

Answer 3

Manufacturing:

Concrete brick are formed in a mold and then allowed to cure (preferably for about 28 days).  Clay brick are cut from a block of clay and kiln-fired after the addition of various powders to achieve the desired color.

Usage:

Clay brick have lower water absorption rates, higher strength (up to 5,000psi vs 1,200-1,800psi), have higher heat resistance, weather better, hold their color better (vs colored concrete).  Concrete brick are mainly used for walkways, patios and fill-ins on concrete walls.  Clay brick are used for building veneers, patios, walkways, retaining walls and more.
