Demonstration for Practical Usage of High Quality Recycled Aggregate

Abstract

Three kinds of high quality recycled aggregate reclamation methods, the heating and grinding method, the mechanical grinding method as well as the screw grinding method, were confirmed their aggregate quality. Recovering from various original concretes, these methods achieved the ordinary aggregate quality standard. Real scale models such as wall models, a building model, mass concrete models etc., demonstrated the recycled aggregate concrete is equivalent performance to the ordinary aggregate concrete.
