摘　　要：通过显微硬度法,分析了用水量波动、水灰比、粉煤灰三者对混凝土匀质性的影响,结果表明,离析度、集料离差度与用水量存在较好的线性相关性;水灰比的降低、粉煤灰的掺入优化了水化产物,降低了孔隙率,有效地改善界面过渡区的均匀性。Through the microscope hardness method, analyzed the influence of water consumption fluctuation, water cement ratio, fly ash to con-crete homogeneity. The results showed that the degree of segregation and diversity of aggregate had a linear relationship to water consumption of con-crete. The decrease of water-binder ratio and fly ash can optimize the hydration products, reduce the porosity, effectively improve the ITZ of concrete.
