Anotācija Latvian Researchers and scientists trying to find the best way of waste recycling and useful application have been strongly interested in wastes from industry until now. One of the main tasks of researchers was to transform industrial wastes to materials, which are not hazardous to the environment and harmful to the human health. According to Latvian policy of waste recycling, which are based on EC legislation of waste processing and disposal, where is written: “pollutant is paying”, Latvian producers are starting to take part in those activities. In reality, the deposition and storage of industrial wastes is very expensive procedure, and the taxes are increasing even more yearly. Industrial producers are interested to use wastes as a raw material for production of new products, which could be competitive in Latvian market. Waste, which comes from recycling process of alumina scrap metals, normally is used in building industry in Europe for production of specific building materials. That experience is taken in to account for creation of heat resistant mortars by using wastes containing aluminium and alumina. Both chemical and mineralogical content of wastes was identified. Stability of wastes in natural environment as well as the degree of hazard was determined. New heat resistant sub-products from wastes were created and tested. Samples of heat resistant mortars were obtained by using clay with high carbonate content, shamotte, inorganic binder and wastes from recycling process of alumina scrap metals. Obtained samples were kept in the room conditions for first 3 days. The primary strength of samples was obtained in initial period of hardening. Final strength and physical properties were obtained after treatment of samples in temperature 1100oC. Samples were tested according to LVS EN standards.
