摘  要:随着严酷环境下各类复杂混凝土结构工程的增加,具有高耐久、高工作性能的高性能混凝土成为关注的焦点。水泥是混凝土的重要组分,其品质影响着混凝土的工作性、力学性能和耐久性能。而传统的普通混凝土均以强度为目标进行设计,对混凝土质量的验收也多以强度为判断准则,导致混凝土生产人员片面追求水泥的强度而忽略了其他品质,造成近年来混凝土结构耐久性问题日益突出,影响混凝土的服役寿命。本文就水泥各项品质对高性能混凝土性能的影响进行分析,并提出高性能混凝土对水泥品质的基本要求。With the increase of concrete structures under complex environment, the high performance concrete with high durability and workability has become the focus of attention. Cement is an important component of concrete, and its quality affects the workability, mechanical properties and durability of concrete. However, Conventional concrete is designed with strength criterion and its quality acceptance is also based on the strength. A large number of professions pursue the strength of cement and neglect its other qualities, which causes the decrease of durability of concrete structure and affects its service life. Therefore, this paper analyzes the influence of the quality of cement on the performance of high performance concrete, and puts forward some basic requirements of high performance concrete to the quality of cement.
