摘　　要：文章通过试验的方式探讨了掺加不同粉煤灰品质的水工混凝土性能,可为大体积水工混凝土方案设计提供科学参考。试验表明:掺加Ⅰ级粉煤灰的试样极限拉伸值、轴拉强度和抗压强度略高于掺Ⅱ级粉煤灰的试样,但其抗冻性能劣于掺Ⅱ级粉煤灰试样;水胶比和强度等级相同情况下,掺加Ⅰ级粉煤灰的试样抗冲磨强度稍高于掺Ⅱ级粉煤灰的试样。In this paper,the performance of hydraulic concrete with different fly ash quality is discussed by means of experiment,which can provide scientific reference for the design of large-volume hydraulic concrete scheme.The results show that the limiting extended value,axial tensile strength and compressive strength mixed with fly ash of gradeⅠare slightly higher than those of fly ash,but the frost resistance is inferior to that of fly ash of grade.Under the condition of the same water-binder ratio and strength grade,the anti-abrasive strength of the sample mixed with fly ash of gradeⅠis slightly higher than that mixed with fly ash of gradeⅡ.
