摘　　要：对不同标准的粉煤灰品质划分指标进行了对比,并用复合因子法对现有研究中的低品质粉煤灰的品质进行了综合评价,对低品质粉煤灰制备结构混凝土的力学性能、耐久性能和构件受力性能的现有研究结果进行了分析。已有研究表明,经过合理的品质指标选择以及配合比设计,低品质粉煤灰可用于结构混凝土。建议通过进一步的研究和试验论证,逐步完善粉煤灰品质评价标准,促进低品质粉煤灰在结构混凝土中的应用。The quality classification index of fly ash in different national standards were compared. The quality of low quality fly ash in the existing research was comprehensively evaluated using the composite factor method. The research progress of structural concrete made of low quality fly ash was discussed, including mechanical properties, durability, and structural member properties. The results showed that low quality fly ash can be used for structural concrete if reasonable quality indicators and proper mix proportion design are properly used. Further research and experimental verification are required to gradually improve the fly ash quality evaluation standard to promote the application of low quality fly ash in structural concrete.
