Název v původním jazyce

Effective use of construction and demolition waste and stone dust in construction for the production of manufactured aggregates in two pilot regions of the Czech Republic

Popis výsledku v původním jazyce

The authors present a unique possibility of utilizing hitherto unused and difficult-to-store types ofwaste such as dust generated during the extraction and treatment of a natural stone, and still difficultto recycle part of construction and demolition waste - residual mineral inert material. Stone dust mixedwith residual mineral inert material, water, and binders in various proportions formed five types ofmixtures which were transformed into manufactured aggregates using hyper-pressing. The propertiesof these manufactured aggregates - resistance to crushing and bulk density - presented on laboratory--based samples were similar to those of natural aggregates. The production of manufactured aggregates,the processing of unused types of construction and demolition waste, together with stone dust, fullycomply with the rules of circular economics. The availability of stone dust has been checked based ondata obtained by personally interviewing the authors in the quarries of the pilot regions of SouthBohemia and Pilsen. Data on the amount of construction and demolition waste produced were obtainedfrom the publicly available database of produced construction and demolition waste - Waste ManagementInformation System (ISOH).
