Research on processing technology of construction waste recycled aggregate
This paper deeply studies the processing technology of construction waste recycled aggregate,aiming to improve the resource utilization efficiency and product quality of construction waste . Several typical process technology routes were proposed,and experimental and comparative studies are carried out,and the effects of different production processes on the quality of recycled aggregate are obtained,including key parameters such as apparent density,water absorption,needle flake particle content,crushing value and particle gradation. The study shows that the jaw breaking+impact+two-stage screening process performed better in multiple param-eters,while the impact+screening+impact+screening process performed better in reducing the needle flake content. At the same time,it points out that in order to improve the quality of recycled aggregate and meet the stricter water absorption requirements,it is recommended to carry out brick-concrete separation treatment. This study provides a scientific basis for the efficient processing and application of recycled aggregates from construction waste,and is of great significance for promoting the resource utilization of construction waste.
