摘　　要：石灰石粉于20世纪90年代由日本首次应用于混凝土,随后因其优异的力学性能和更合理的经济效果蓬勃发展。目前,石灰石粉混凝土在道路、桥梁、水工混凝土等实际工程中拥有广阔应用前景。主要综述了石灰石粉混凝土基本工作性能和力学性能,并对其干缩性能、抗碳化性能、抗氯离子侵蚀性能、抗冻性能和抗硫酸盐侵蚀等耐久性能研究进行了相关介绍。最后,结合目前石灰石粉混凝土研究现状,进一步提出了其研究方向。Limestone powder was first used in concrete by Japan in the 1990s,followed by vigorous development due to its excellent mechanical properties and a more reasonable economic effect.At present,Limestone powder concrete has broad application prospects in the road,bridge,hydraulic concrete and other practical projects.In this paper,the work performance and mechanical properties of limestone powder concrete were reviewed and the durability properties such dry shrinkage performance,carbonation resistance,resistance to chloride ion attack,frost resistanceand resistance to sulfate attack were carried out the relevant introduction.Finally,the research direction was put forward based on the current research situation of limestone powder concrete.
