CEBs differ from mud bricks in that the latter are not compressed, but solidify through chemical changes that take place as they air dry. The compression strength of properly made CEB usually exceeds that of typical mud brick. Building standards have been developed for CEB. CEBs are assembled onto walls using standard bricklaying and masonry ...
Clay engineering bricks are defined in § 6.4.51 of British Standard BS ISO 6707-1;2014 (buildings & civil engineering works - vocabulary - general terms) as "fire-clay brick that has a dense and strong semi-vitreous body and which conforms to defined limits for water absorption and compressive strength".

The compressive strength of bricks produced in the United States ranges from about 7 to 103 MPa (1,000 to 15,000 lbf/in 2), varying according to the use to which the brick are to be put. In England clay bricks can have strengths of up to 100 MPa, although a common house brick is likely to show a range of 20–40 MPa.
Fly ash bricks. Fly ash brick (FAB) is a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 °C steam bath, then toughened with an air entrainment agent, the bricks can last for more than 100 freeze-thaw cycles.
Measuring the compressive strength of a steel drum. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled apart).
The compressive strength of rammed earth is dictated by factors such as soil type, particle size distribution, amount of compaction, moisture content of the mix and type/amount of stabiliser used. Well-produced cement-stabilised rammed earth walls can be anywhere between 5 and 20 MPa (700 and 3,000 psi) [ citation needed ] .
Acid brick is created from high silica shale and fired at higher temperatures than those used for conventional brick. Some manufacturers create the brick by baking it for over a week. It has an average compressive strength of approximately 23,000 PSI. The ASTM specification C-279
Engineers usually specify the required compressive strength of concrete, which is normally given as the 28-day compressive strength in megapascals (MPa) or pounds per square inch (psi). Twenty eight days is a long wait to determine if desired strengths are going to be obtained, so three-day and seven-day strengths can be useful to predict the ...
