An Experimental Study on the Influence of Moisture State of Aggregates on the Properties of the Recycled Aggregate Concrete

재생골재 콘크리트의 특성에 대한 골재 함수상태의 영향에 관한 실험적 연구

The objective of this experimental study is to grasp an influence of moisture state of aggregate on the characteristics of the recycled aggregate concrete. The moisture states of the aggregates were controlled at prewetted, oven-dried and saturated surface-dried states prior to use. To maintain the designed mix proportioning unchanged, the amounts of water and aggregates used in mixing were adjusted according to the actual moisture contents of the aggregates. Test results showed that the saturated surface-dried state aggregate concretes exhibited the highest compressive strength.
