applied materials and technologies for modern manufacturing: study strength of recycled concrete mix design
the recycled concrete mixes contained recycled aggregate and natural fine sand, while the normal concrete mixes contained all natural coarse and fine aggregates. table 1.
process; or recycled aggregates which tend to be crushed concrete from demolition or waste. recycled aggregates are further sub categorised as: n ra (recycled aggregate), which is comprised of any inorganic material previously used in construction and can include a high proportion of masonry n and rca (recycled concrete aggregate) which is comprised of crushed concrete.
