摘　　要：根据国内外混凝土材料循环利用的研究发展现状,提出了混凝土材料完全循环利用的可能性,具体分析了混凝土材料完全循环利用的途径和方法,并通过实验证实了混凝土材料可以多次循环利用,从而实现混凝土材料的生态化生产和使用.Huge amount of concrete debris is being discharged after the concrete structures are demolished, while the quality raw materials for the manufacture of cement and concrete is becoming shortage with the coming of the fastigium of infrastructural constructions in our country. The concrete wastes can be reused as recycled aggregates or raw materials for production of cement. The techniques and approach to reuse the concrete wastes are proposed from the achievements in this field. Test results have shown the possibility of completely recycling concrete and thereby re alizing the ecological applications and production of cement and concrete.
