| 摘 要： | 本文主要研究了单掺石灰石粉、石灰石粉与粉煤灰复掺对泵送混凝土拌合物工作性和抗压强度的影响，研究表明：掺加石灰石粉可以改善泵送混凝土的工作性能，与单掺石灰石粉相比，石灰石粉与粉煤灰复掺，具有复合叠加效应，不仅可以改善泵送混凝土的工作性能，同时可提高泵送混凝土的抗压强度。

| Abstract: | Influence of single limestone powder admixture and compound limestone powder and fly ash admixture on the workability of pumped concrete mixture and compressive strength was studied in this paper. The results show that limestone powder admixture can improve the workability of pumped concrete. Compared with single admixture of limestone powder, compound admixture of limestone powder and fly ash can both improve the workability and increase the compressive strength of pumped concrete. |
