Various industrial wastes, produced by high temperature manufacturing procedures, as well as some natural rocks, are characterized by high amount of glassy phase between 70 and 100 %. This peculiarity gives the possibility to obtain cheap sintered glass-ceramic like materials without melting procedure by using only sinter-crystallization heat-treatment. In present work are shown preliminary results about the sinter-crystallization behaviour of three different materials: vitrified municipal solid waste bottom ash, granulated blast furnace slag and alkaline basaltic tuffs. The sintering and crystallization were studied by dilatometry and DTA, respectively. The initial and final phase compositions were evaluated by XRD analysis. The total porosity of the final sintering samples was evaluated by pycnometric techniques.

Abstract
Various industrial wastes, produced by high temperature manufacturing procedures, as well as some natural rocks, are characterized by high amount of glassy phase between 70 and 100 %. This peculiarity gives the possibility to obtain cheap sintered glass-ceramic like materials without melting procedure by using only sinter-crystallization heat-treatment. In present work are shown preliminary results about the sinter-crystallization behaviour of three different materials: vitrified municipal solid waste bottom ash, granulated blast furnace slag and alkaline basaltic tuffs. The sintering and crystallization were studied by dilatometry and DTA, respectively. The initial and final phase compositions were evaluated by XRD analysis. The total porosity of the final sintering samples was evaluated by pycnometric techniques.Pubblicazioni consigliate
