利用以石灰岩为粗骨料的废弃混凝土的全部组分取代全部粘土和部分石灰石作为水泥原料，再添加一定量的校正原料，配料后可以烧制再生水泥熟料，是一条保护环境、节约资源、可持续发展的技术路线。“,”This paper proposed to use all components of waste cement concrete with limestone coarse aggregates as the raw materials of cement. Recycling cement clinker will be produced in this way by sintering waste concrete and a certain amount of accessory materials. It is a technical route of protection environment,resource conservation and sustainable development.
