This paper reviews the long‐term properties of recycled aggregate concrete (RAC) including long‐term strength shrinkage creep carbonation resistance antifreeze resistance impermeability abrasion resistance alkaline aggregate reactions sulphate corrosion and fatigue behaviour Most studies have shown that the long‐term properties of RAC are inferior to those of natural aggregate

Properties and Durability of Aggregate

The physical properties of aggregates stem from the inherent properties of the source rock these include texture structure and mineral composition Textural properties give rise to internal characteristics of which the pore size is perhaps most important Structural characteristics define the degree to which the minerals within the aggregate are segregated or oriented in one direction
