摘　　要：在“碳达峰、碳中和”背景下,水泥行业需降低碳排放并规模化消纳CO_(2).低钙硅酸盐胶凝材料作为一种新型固碳胶凝材料,具有节能减排、碳化活性高和产物稳定等优势,可有效推动水泥行业低碳转型.本文系统归纳了不同低钙硅酸盐胶凝材料体系的配料组成、烧成制度、矿物组成和碳化硬化性能等研究进展,展望了低钙硅酸盐胶凝材料的研究方向,以期为低钙硅酸盐胶凝材料的发展提供借鉴.Under the background of“carbon peak and carbon neutrality”,reducing carbon emissions in the cement industry and achieving large-scale CO_(2) sequestration have become an urgent issue.Low-calcium silicate cementitious material,as a new type of CO_(2) sequestrating material,possesses advantages such as energy saving,high carbonation reactivity,and stable products,and is considered an effective pathway for the low-carbon transformation of the cement industry.This paper starts with different low-calcium silicate cementitious material systems,systematically summarizes the research progress of the mix proportion,firing system,mineral composition,carbonation and hardening properties of low-calcium silicate minerals.The future research directions of low-calcium silicate cementitious materials were discussed,in order to provide reference for the development of low-calcium silicate cementitious materials.
