Influence of Physical Strengthening Technology on the Properties of Recycled Coarse Aggregate
This paper studied the properties improvement of recycled coarse aggregate by the physical strengthening technology (particle-shaping method).Through the analysis for obtained properties which consist of density, crush index, bulk density and water absorption.etc of recycled coarse aggregates in different strengthening technologies, the categories of recycled coarse aggregate could be assessed and determined.The results showed that ordinary recycled coarse aggregates that was handled twice by using particle shaping equipment can achieve the standard of class Iaggregates and its water absorption ratio at 24h was 1.2%, the apparent density reached 2575kg/m3, crush index value was 9%, the void ratio was 45%, all property parameters were close to those of natural coarse aggregate.
