Prospects for the Utilization of Mineral Admixture Preparation by MSWI Fly Ash
The utilizing municipal solid waste incineration(MSWI)fly ash for produce mineral admixtures is prepared in order to achieve the resource utilization.The typical mega city of Shanghai is taken as an example.Firstly,the production,disposal status of MSWI fly ash and the evolution of related policies in Shanghai were analyzed;Secondly,the research status of MSWI fly ash resource utilization technology at home and abroad were analyzed to propose a resource utilization path for preparing mineral admixtures,which involves harmless treatment of MSWI fly ash and mixing it with slag powder in a certain proportion to prepare mineral admixtures for cement or concrete;Finally,the feasibility of the plan was analyzed from the aspects of supply and demand matching,technological feasibility,eco-nomic benefits,simple process,and feasible equipment.The application potential of the plan in scenarios such as foundation treatment,road base,and dry powder mortar was explored.This research result can provide reference for exploring the resource utilization of MSWI fly ash and building a waste-free city.
