摘　　要：选取化学成分SiO2和Al2O3总含量相近的Ⅰ级粉煤灰和Ⅲ级粉煤灰配制中、高掺量粉煤灰混凝土,再测试其7,28,90 d抗压强度、抗氯离子渗透性能及抗钢筋锈蚀性能.结果表明:在本试验条件下,同样配合比的I,Ⅲ级粉煤灰混凝土的抗压强度、抗氯离子渗透性能和抗钢筋锈蚀性能并无明显差别.试验结果同时表明,目前用于结构混凝土中的粉煤灰的评价体系尚有待改进.Concrete with medium or high volume （;lass Ⅰ and Class Ⅲ fly ash was designed according to the activity of fly ash, and the 7, 28, 90 d compressive strength, the anti-chloride ion per meability and the antieorrosion behavior of concrete were tested. The test results show that the compressive strength, the anti-chloride ion permeability and the anticorrosion behavior of the Class Ⅲ fly ash concrete are not notably lower than that of the Class Ⅰ fly ash concrete, and the evaluating system of fly ash needs to be improved.
