摘　　要：通过试验分析了高温稻壳灰的各项性能,并通过研究稻壳灰粉磨细度和活性确定了稻壳灰粉磨时间为30min,通过胶砂和混凝土试验确定了稻壳灰作混凝土掺合料的适宜掺量为20%,采用电通量法研究了稻壳灰对混凝土氯离子渗透性的影响,结果表明,掺20%稻壳灰后混凝土抗氯离子渗透性能得到改善。The performance of high-temperature rice husk ash is analyzed. It is determined that the grinding time is 30 minutes by studying the activity and grinding fineness of rice husk ash, and the optimal content of rice husk ash is 20% in the cementitious material by mortar and concrete tests. In addition, the chloride ion penetration of concrete is studied using the electric flux method. The result shows that the chloride ion penetration of concrete is improved when 20% of the rice husk ash is added in concrete.
