| 摘 要： | 以不同比例石粉和粉煤灰复掺50％取代水泥配置混凝土进行试验.研究了石粉和粉煤灰复掺比例对混凝土抗压强度和收缩率的影响,利用XRD和TEM对复掺混凝土的水化产物进行了分析.结果表明:由于石粉和粉煤灰对混凝土抗压强度的影响机理不同,复掺比例在不同龄期对混凝土抗压强度的影响规律也不同；复掺混凝土的收缩率随复掺料中石粉含量的增加而变大.

| 关 键 词： | 石粉 粉煤灰 抗压强度 收缩率 耐久性 |

| Abstract: | The concrete 50% of the cements were replaced by limestone powder and fly ash in different ratio.The influence of mixed ratio on compressive strength and shrinkage rate of the concrete was studied,and hydration products were analyzed by XRD and TEM.The results showed that influence law of doping ratio on compressive strength of concrete in different curing period is difference because influence mechanism of limestone powder and fly ash on compressive strength is difference.Shrinkage rate of modified concrete improves with the increase of the limestone powder in admixture. |

| Keywords: | limestone powder fly ash compressive strength shrinkage rate durability |
