Using pore-forming agents to reduce energy demand

Summary

The addition of carbon or inorganic compounds such as Styrofoam, sawdust, coal slag or waste material from the paper industry to ceramic mixes can reduce energy consumption for the production and improvement of the functional properties of ceramic building materials.  During  the firing process, the conversion of these additives leads to hollow spaces which improves thermal insulation. In addition, energy for the combustion process is released by conversion of the organic substances.  6 refs.
