Coarse Ceramic Products for the Construction Industry

Coarse ceramic products are tiles and hard bricks 

The clay products used in the construction industry are so-called coarse ceramic products. They include bricks, roofing tiles, clinkers (hard bricks), drainpipes and protection covers for cables. The manufacture of such products hardly differs from that described in Section 5.5.3 for the general manufacture of ceramic products. 

tile clay, clay stone and shaly clay are used as raw materials in the manufacture of tiles. The chemical composition of the raw materials is similar to that for the manufacture of fine ceramic products (see Section 5.5). The quantities of impurities can, however, be higher. 

Light construction materials are of particular interest in the construction industry. The manufacture of light tiles can be achieved using different processes  

Light bricks are manufactured almost exclusively by the incorporation of expanded polystyrene beads and/or sawdust.
