Carbonation of Aggregates from Construction and Demolition Waste Applied to Concrete: A Review

The construction industry is essential to the development and economy, but also largest generator of demolition waste (CDW). While efforts are made minimize such generation, has been developing applications for it in form aggregates replace commonly used natural aggregates. However, structural applications, necessary ensure that properties concrete produced with CDW, as recycled (CDW-concrete), guarantee adequate performance do not put structure at risk. For this, one alternatives improving CDW through carbonation, a process called carbonate curing or accelerated carbonation. In this sense, paper aims investigate carbonation aggregates, clarifying how occurs, existing methods, main affect process, their influence on CDW-concrete. To end, SREE (systematic review engineering experiments) method was search analyze scientific manuscripts published without time limit. results revealed most widely recommended by Chinese standard GB50082, highlighted need further research CDW-concrete, focusing its eco-friendly potential capture CO2 from atmosphere.
