1 Context and formulation of problem

Low-temperature drying is a modified form of open-air drying with the aid of modern plant and control technology. In heavy clay production, the introduction of low-temperature drying enables dissolution of the energy ­inefficient kiln/dryer closed heat cycle. For the advancement of this technological step forward, it is very important that the green brick strength be enhanced, parti­cularly during the initial, shrinkage-attended stage of drying. Higher strength makes it possible for the material to tolerate without cracking the high shrinkage stresses...
