Abstract
- New heat-insulating materials were prepared via the combined use of local technogenic and natural raw materials. The mixtures of natural clay, overburden of polymetallic surface mine, charcoal chips, wood crumbs, dolomite chips, and minor amounts of triethanolamine as a hardener and stearic acid emulsion as a waterproofing agent were used as starting mixtures. For the ceramic-like materials prepared by firing at 1000оC, we report their physicomechanical parameters-shrinkage ɛ, density d, abradability a, water adsorption q, thermal conductivity k (at 50oC), and compressive strength σс. The synthesized ceramic masses may find their application in the fabrication of wall panels and lightweight concrete aggregates. [ABSTRACT FROM AUTHOR]
