| description | The paper is dedicated to waste processing management in waste processing technology. Processing of scrap concrete waste, similar in composition and condition to traditional raw materials, is economically and ecologically feasible. Secondary crushed stone obtained by crushing scrap of reinforced concrete panels in demolished five-storey apartment blocks of the first phase was studied. It is shown that concrete with scrap concrete waste shows strength properties similar to primary concrete and helps organize waste-free production. The methods of recycled waste usage, especially usage of secondary crushed stone made of crushed concrete scrap, are becoming ever more relevant with every passing year. Imported concrete aggregate volumes can be reduced by 15-30% due to usage of secondary crushed stone. Consideration of industrial waste problem and methods of solving this problem by using waste in construction industry, including secondary crushed stone made of crushed concrete scrap, is made. Annually, about 11.5 million tons of construction waste is generated in Moscow. The use of industrial waste similar in terms of composition and condition of traditional raw materials unquestionable from economic and environmental point of view. This study showed that concrete using fine granulated blast furnace slag as cement additives has higher initial strength characteristics. |
