A Study on the Qualities of Recycled Fine Aggregate and Properties of Recycled Concrete Producted by the Drying Manufacturing Method
건식제조법에 의해 생산된 고품질 재생잔골재의 품질 및 재생콘크리트의 성상에 관한 연구
Abstract
The purpose of this study is to investigate quality of recycled fine aggregate manufactured by drying manufacturing system which is the manufacture method of high quality recycled fine aggregate, and to analyze on the fresh, hardened and durability properties of recycled concrete using it. Therefore it is to present the fundamental data for structural application of recycled concrete. The results of this study are as follows; Quality of recycled fine aggregate by drying manufacturing system is improved, and compressive and tensile strength of recycled concrete using high quality recycled fine aggregate are similar to those of normal concrete. But, durability such as carbonation, salt damage and dry shrinkage show decreased somewhat.
