Abstract: The use of cement with reduced clinker content or the reuse of concrete waste provided by the demolition of buildings in recycled aggregate concrete (RC) leads to a reduction of the environmental impact of concrete production. In Switzerland, there is a combination of these two approaches applied for house building. However, due to a lack of data the carbonation resistance of RC and with it the durability of buildings constructed with it are scrutinised. In this study, the carbonation resistance of RC with the typical composition used in the Swiss building industry is investigated to clarify the influence of recycled aggregate and type of cement used. RC with two different replacement levels of natural aggregates is produced using three different blended cements.
