复合胶凝材料性能研究现状简述

State-of-the-arts of Research on Material Properties of Composite Cementitious Materials

混凝土是当今社会用量最大的建筑材料之一。然而预拌混凝土行业属于高能耗、污染相对严重的低门槛行业,对如今倡导的低碳理念带来较大的挑战。水泥是混凝土中重要的原材料,生产过程会产生大量的CO_(2)排放和能源消耗,因此采用复合胶凝材料代替水泥制备混凝土是混凝土实现低碳化的关键环节。本文通过对可代替水泥制备混凝土的复合胶凝材料的研究进展进行总结,并阐述它们目前研究的不足进而提出未来展望,为复合胶凝材料未来的应用提供依据。

Concrete is one of the most widely used building materials in today's society.However,the ready-mixed concrete industry is a low-threshold industry with high energy consumption and relatively serious pollution,which poses a great challenge to the low-carbon concept advocated today.Cement is an important raw material in concrete,the preparation process will produce a lot of CO_(2) emissions and energy consumption,so the use of composite cementitious materials instead of cement to prepare concrete is a key link to achieve low carbonization of concrete.This paper summarizes the research progress of composite cementitious materials that can replace cement to prepare concrete,and expounds the shortcomings of their current research and puts forward the future prospects,providing basis for the future application of composite cementitious materials.
