A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote rectangular units made of clay-bearing soil, sand, and lime, or concrete materials. Bricks can be joined together using mortar, adhesives or by interlocking them.
We produce a special quality of lime for calcium silicate (sand-lime) bricks that makes them especially simple to work with. Only natural raw materials are used; a mixture of 'natural' calcic lime, sand and water is pre-formed in presses. The result is hardened in autoclaves under steam pressure at temperatures between 160°C and 200°C.
