Clay materials for buildings. Properties and products

The material properties of clay products are linked to the quantity of clay within the initial blend and the porosity obtained. According to the mixture and process, the ceramic body can have little porosity (roof tile and pavement), or be very porous with good thermal insulation properties which are used in the production of a certain type of bricks. This article presents the main products of the heavy clay industry such as facing bricks, perforated bricks, insulating bricks and various roofing tiles (plain tiles, over and under tiles as well as interlocking tiles). It also mentions cladding, clay flue blocks and pavements.
