Original Abstract

Construction and demolition waste (CDW) reducing is one of the world's and European priorities. Currently, half of the global total waste production occupies CDW, whichgenerates about 3 billion tonnes of this waste per year. In order to create sustainable construction principles, recycled aggregate (RA), which is a significant component of the concrete composition, needs to be efficiently utilized to exploit its full potential. Production of a conventional concrete from recycled aggregates has long been the subject of scientific interest. Physical and mechanical properties of original concrete as well as characteristics of RA are significant factors influencing final recycled aggregate concrete (RAC), especially when used in structural concrete. Legislative documents, standards, and guidelines are formulated in different countries around the world, specifying the requirements for RAC properties, including the proportion of total aggregate replacement and other characteristics. Differences in RA and RAC requirements across documents vary greatly and are subject to continuous changes. The article aims to fill the literature gap by an actual and comprehensive compendium of standards and guidelines requirements across countries that are engaged in the issue of RAC production. The conclusion of the article deals with differences in particular countries and proposes further developments in the field of standardization of concrete recycling.
