Abstract
In this study, we analyzed the problems of existing construction waste shredding technology to diagnose the problems of low quality recycled aggregates and to develop a new mortar peeling technique to produce high-quality recycled coarse aggregate for concrete. The purpose of this study is to verify the effectiveness of mortar peeling technique by doing simulation prior to on-site application and to check the quality properties of recycled coarse aggregate produced by applying a mortar peeling technique. We manufactured and installed High speed Rotating Grinder on-site and analyzed the correlation between mortar adhesion amount, dry density and water absorption rate of recycled coarse aggregate.
