The use of technogenic carbon in gypsum compositions for green building

The publication is devoted to the study of possibility using ash and slag waste from hydraulic removal fuel power plants in production building gypsum materials. These wastes are not used industrial due heterogeneity composition properties. This a big unresolved problem for many thermal plants. However, when separating individual parts - carbon, aluminosilicate or magnetite selected part component increases. paper considers use carbon as an additive compositions. A comparative analysis properties compositions modified with additives given. higher efficiency lightweight has been established. comparison was carried out terms compressive strength average density. Additives were introduced amount up 30%. ratio tensile density mixtures characterized by specific strength. It additive. introduction porous mineral fillers perlite vermiculite volume 20% contributed even greater decrease best result shown addition perlite. They can be green building.
