工程弃渣制备砂石骨料技术研究和应用

Study and Application of Sand and Gravel Aggregate Production from Engineering Waste Slag

工程建设中通常产生大量的工程弃渣,同时又需要大量的砂石骨料。为解决工程弃渣处理困难,缓解砂石骨料供需矛盾,达到工程建设与环境保护之间的和谐,通过依托部分水电站工程充分利用工程弃渣制备砂石骨料的实例,研判未来发展趋势,归纳分析工程弃渣利用的可行性,重点研究解决工程弃渣制备砂石骨料关键技术,明确其质量控制要点,为工程弃渣制备砂石骨料提供全面、系统的技术支撑。

In engineering construction,a huge amount of waste slags is usually generated and a large quantity of sand and gravel aggregates is required as well.This paper studies and analyzes the development trend and feasibility of waste slag utilization based on the cases of producing sand and gravel aggregates from waste slags in some hydropower projects.It tends to provide solutions to the disposal problem of waste slag and the supplydemand contradiction of sand and gravel aggregate,achieving balance in construction and environment.The paper focuses on the key technologies of waste slag utilization for sand and gravel aggregate as well as quality control method,providing overall and systematic technical support for sand and gravel aggregate production.
