摘　　要：分析了河南省西峡县桑坪石灰岭石灰石在混凝土中应用的必要性,通过在粉煤灰混凝土中掺加石灰石粉取代部分粉煤灰,检验不同组成材料下的混凝土性能,研究石灰石粉对混凝土强度和工作性的影响,进一步确定满足混凝土性能的石灰石粉的合理掺量,保证石灰石粉科学、有效地应用于混凝土工程中。This thesis first analyzed the necessity for the application of limestone powder produced in Lime Ridge from Xixia County, Henan Province.It also tested the concrete performance with different composition materials and did research on the influence of limestone powder on concrete strength by adding limestone powder instead of fly ash in fly ash concrete.It then found out the reasonable volume of limestone powder to meet the concrete＇s performance, in order to guarantee the scientific and effective use of limestone powder in concrete engineering.

关 键 词：石灰石粉 石灰石粉掺量 混凝土性能
