Abstract:
Cellular solids are highly porous materials resulting from the insertion of a gaseous phase into a solid phase, which may be ceramic, metallic, polymeric or composite, with characteristics depending on the material of this solid. Foams glasses are examples of these glasses structure materials and are mostly used as thermal and acoustic insulation. Foams glasses are obtained by the addition of a porogenic/foaming agent to the finely milled glass and heated at temperatures above its softening point. The ornamental rocks are basically subdivided into granites and marbles. Like marble, the carbonate rocks generally fit. In the processing of the blocks in the sawmills, the waste generated is 40% of the volume of the block processed. It is estimated that about 1.5 Mt of the fine wastes (stone dust) are generated annually in Brazil. The objective of this work was to characterize a beverage packaging glass waste for use as a matrix and a marble waste for use as foaming agent in the development of foams glasses. The wastes were characterized by chemical, mineralogical, particle size distribution, thermal and morphological analysis. The results proved that the wastes are able to develop foams glasses for the desired purposes, glass waste as matrix and marble waste as foaming agent.
