GYSJ0250C aggregate screen machine is a piece of patented road maintenance equipment, which is designed for micro surfacing construction. Due to its large aggregate bin capacity (10m 3), our aggregate screen machine can provide materials for several microsurfacing pavers is equipped with aggregate proportioning equipment controlled by frequencyvariable speed regulation .
Concrete produced from recycled aggregates is likely to be used for structures of average span and in conditions of low aggressively. However, the study of recycled concrete microstructure and their durability can complete and improve this study. Such a study can extend the usage range of recycled aggregatesbased concrete in civil engineering.
