A review of recycled aggregate in concrete

Durability of recycled aggregate concrete - A review ...

Although the researches on recycled aggregate concrete (RAC) has been going on for nearly 70 years , the use of RA in concrete structures is still limited due to its long-term durability concerns. With the decrease of natural aggregate resources and the increase of waste concrete generation, RAC has become a hot research topic around the world.
