Brick - Wikipedia
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term brick denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks.Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are produced in numerous classes, types, …
