Possibilities of Using Pumice Aggregates into Thermal Insulation Lining of Industrial Chimneys

Abstract

This paper deals with the possibility of using pumice aggregates into thermal insulation lining of industrial chimneys. It introduces the construction of modern chimneys and mentions possible risks and degradation processes associated with condensate penetration. In the experiment, mixtures with pumice as aggregate were prepared. The thermal insulation properties, compressive strengths and the resistance to sulphates in a 5% sodium sulphate solution were evaluated and compared.
