Highly porous bricks are produced from granules of clay-coated sawdust particles to achieve a lower apparent density than that of conventionally produced bricks

摘要

Highly porous brick are produced from granules of clay-coated sawdust particles. A highly porous brick is produced by mixing sawdust with water, adding ground clay optionally premixed with an inert filler, granulating to form clay-coated sawdust particles, and then pressing, drying and firing.
