RECYCLING SYSTEM OF CONCRETE WASTE INCURRED FROM BUILDING DEMOLITION : Long-term properties of recycled coarse aggregate concrete produced by means of the aggregate replacing method(Materials and Construction)

Abstract

The recycled aggregate concrete produced by the aggregate replacing method was applied to the actual structure. This paper describes various properties of recycled coarse aggregate and recycled aggregate concrete produced by the actual concrete plant. Specifically, long-term properties of recycled aggregate concrete and normal aggregate concrete, such as strength, elasticity, and durability, was confirmed in duration of two years. As a result it is confirmed that recycled aggregate concrete has the performance equivalent to regular concrete made of normal aggregates, at in situ condition during two years.
