Durability Studies on the Recycled Aggregate Concrete in ...

Jul 28, 2019  Since China hosted the Olympic Games in 2008, a mass of construction and demolition (CD) wastes were produced with the rapid urbanization construction. Recycling the CD waste into recycled aggregates (RA) is an effective method for reducing the amount of CD wastes. Many studies on the properties of RA and the durability of recycled aggregate concrete (RAC) were conducted in
