Critical Review on Types of Bricks Type 8: Concrete Bricks

Abstract
Brick is the most commonly used building material for construction. The CO2 emissions in the brick manufacturing process affects the green environment. Therefore, focus should be now more on seeking eco – friendly solutions for greener environment. The conventional masonry unit used is clay bricks for construction of masonry works but with advancement of time these clay bricks were replaced by fly ash bricks of same size But with respect to time due to advancement in technologies concrete blocks of size varying as per the purpose of masonry work is being on the use This research paper presents the introduction to such masonry units through its manufacturing process and various tests.The use of concrete masonry units for high rise load bearing construction has created a need for concrete block with high compressive strength. Keywords - Concrete Bricks, Process of Manufacturing, History, Testing of Brick
