FIELD: chemistry. ^ SUBSTANCE: method relates to production of construction materials, particularly to use of ash from refuse incineration plants for processing solid domestic wastes, followed by recycling thereof in production of highly efficient and environmentally safe construction articles. The method is characterised by that glass mass is obtained from a mixture containing up to 70% ash, 20-40% silica-containing component and up to 20% alkali-containing component. The obtained articles undergo crystallisation in a single step at temperature 900-1100C and holding for 60-120 minutes or in two steps at temperature 700-850C and holding for 30-60 minutes and at temperature 900-1100C for 60-120 minutes. ^ EFFECT: high chemical resistance, wear resistance, prevention of water absorption and environmental safety of the obtained glassceramic material. ^ 4 cl, 1 tbl, 3 ex |
