The Cement Sustainability Initiative

Most recycled concrete is used as aggregate in road sub-base. When well cleaned, the quality of recycled concrete aggregate is generally comparable to virgin aggregate. The possibilities for use are equally comparable although the use of crushed concrete in new fresh concrete is rare. Recycled aggregate accounts for ~6% to 8% of aggregate

Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent. For instance, British standard BS 8500-2 ( BSI, 2006 ) defines RCA as recycled aggregate with maximum masonry/fines content of 5%, maximum lightweight material/asphalt content of 0.5% and maximum other foreign

Report of Recycled Concrete Aggregates

08-08-2019  Summary Fresh concrete made with recycled aggregate tends to be very harsh due to the angular shape and rough surface of the aggregate, require higher water contents due to higher absorption capacity of the cement paste, higher air content due to greater porosity of the recycled aggregates themselves and to the entrained air in the original mortar than concrete made with virgin aggregates
