主 题：Mine backfill paste industrial waste binder powder green environmental protection
摘 要：To improve the economic and social benefits of mining and backfill,it is necessary to find the backfill materials suitable for mineral mining,improve the various properties of the filling materials,and develop low cost,high performance new filling *** cement is neither environmentally friendly nor ***,we have begun to study and apply some industrial waste,such as slag,fly ash,and other solid wastes,with certain activities as the primary component of cementing material that will not only meet the technical requirements of filling,but also comprehensively utilize industrial waste and possess a benign,sustainable lifecycle for environmental *** study expounds the composition and reaction mechanism of alkali-activated binder powder used for cemented paste backfill material,summarizes the research and application status of alkaliactivated binder powders,including mechanics,durability,economic and environmental,and discusses future development directions for mine binder *** needs to continue to expand the utilization range of solid waste and improve the utilization rate of solid waste in the *** development and research of this binder powder plays an important role in the progress of filling ***,the research about alkali-activated binder powder contains great development potential and broad prospects.
