Abstract

This paper describes basic properties of materials composed of fly ash produced during fluid burning. This material is based on alkali-activated fly ash which contains a portion of fly ash produced during fluid burning. Firstly the physical and chemical properties was described for each type of fly ash and fly ash mixture. The new materials composed of fly ash mixture and fly ash may have the similar mechanical and physical properties. The work focused on findingan appropriate technological procedure, the optimum composition of mixtures. Long-term stability was simulated by means of accelerated aging of these materials.
