| 摘 要： | 石灰石粉是指以CaCO3为主要成分、经机械磨细的粉末状材料,石灰石粉已作为水泥混合材被广泛应用于水泥中,并形成了石灰石水泥的相关标准。本文系统阐述了石灰石粉对混凝土工作性能、力学性能和耐久性能的影响,分析了不同研究者对石灰石粉混凝土研究结果差异的原因,提出了石灰石粉应与其他矿物掺合料(如矿渣、粉煤灰)复掺的应用技术途径以及混凝土矿物掺合料规模应用过程应注意的问题。

| Abstract: | Limestone powder refers to the powder materials which be ground by machine,and consist of CaCO3.Limestone powder is widely applied to cement as mineral admixtures.Related standard also has been established.The effect of limestone powder on workability,mechanical property and durability of concrete were studied.The reason for the difference of study on concrete contained limestone powder which carried by different researcher was analysed.Application technological approaches refer to limestone powder should be used combined with other mineral admixtures(Such as slag and fly ash) and Problems should pay more attention during the widely application of limestone powder as mineral admixtures were raised. |
