Clay Engineering bricks are defined in British Standard BS 6100 ‘Glossary of building and civil engineering terms’ as ‘brick sized fired clay units having a dense and strong semi vitreous body, conforming to defined limits for water absorption and compressive strength.’<ref>http://www.georgelines.co.uk/pdf/Engineering%20Bricks%20Technical%20Detail.pdf</ref> |
|||
Stronger and less porous engineering bricks (UK Class A) are usually blue due to the higher firing temperature<ref>http://www.es.ucl.ac.uk/schools/UCL/bricks.htm</ref> whilst class B's are usually red. Class A bricks have a strength of 125N/mm² and water absorption of less than 4.5%, Class B bricks have a strength greater than 75N/mm² and water absorption of less than 7% |
