To address the waste of natural aggregates and limited application of recycled aggregates, this study prepared sand-free macroporous recycled concrete using natural and recycled aggregates. Macro and micro properties of dry, water spraying, and coating sand-free macroporous recycled concrete were investigated via mechanical properties, microhardness, scanning electron microscopy, and X-ray diffraction analysis. The results show that different curing processes affect the hydration reaction of ordinary Portland cement, and sand-free macroporous recycled concrete “honeycomb” structure and recycled aggregate characteristics complicate the hydration process. The best curing method is coating, followed by dry, while water spraying is least effective. Microhardness and scanning electron microscopy tests reveal that the free water absorption in matrix increases during water spraying, resulting in concrete expansion, deteriorating adhesion of aggregate-cement interface and decreasing hardness. X-ray diffraction analysis results confirm the effects of curing methods on sand-free macroporous recycled concrete via composition of hydration products like portlandite.
