摘　　要：文中采用放射性试验方式对水泥和混凝土中的粉煤灰进行检测,对粉煤灰水分及粒径等因素进行控制,进一步分析外部因素对粉煤灰放射性结果的影响,同时结合GB/T 1596—2005《用于水泥和混凝土中的粉煤灰》标准展开结果分析,最终可确认,最新标准更加适用于水泥和混凝土中粉煤灰放射性检测试验,并可对粉煤灰质量加以控制。In this paper,fly ash in cement and concrete is tested by radioactivity experiment,and factors such as moisture and particle size of fly ash are controlled.The influence of external factors on the results of fly ash radioactivity is further analyzed.At the same time,the results are analyzed in combination with the latest GB/T 1596-2005"Fly Ash used in cement and concrete"standard.Finally,it can be confirmed that the latest standard is more suitable for the test of fly ash radioactivity in cement and concrete,and can control the quality of fly ash.
