A Fundamental Study on the Quality of Recycled Aggregate Produced in Recycling Plant

The reuse of waste concrete amy settle the problems of environmental pollution and critical shortage of good natural aggregate. But recycled aggregate particles consist of substantial amount of relatively soft cement paste component. These aggregates are more porous, and les resistant to mechanical actions than natural aggregate. And the source of supply for manufacturing recycled aggregate is generally composed of different types of original aggregate and strengths of original mortar. The properties of recycled aggregate exhibit a considerable variation due to the properties of original concrete. This paper is an experimental study on the fundamental properties of recycled aggregates sampled from processing plant in the suburbs of TaeJeon.
