摘　　要：生物质电厂灰获取便利且具有一定火山灰活性。为测试生物质电厂灰作高性能混凝土掺合料的可行性和性能影响,本文对生物质电厂灰进行了理化特性分析,对灰样进行了预处理,制备了10%,20%和30%掺量的高性能混凝土试块进行了抗压强度试验和抗氯离子渗透性能测试,结果表明以处理后的生物质电厂灰作高性能混凝土的掺合料,随掺量增加,高性能混凝土试块抗压能力减小,但总体满足强度要求;掺入生物质电厂灰可以提高高性能混凝土抗氯离子侵蚀能力。Biomass power plants ash is easy to obtain and has certain volcanic ash activity.To test the feasibility and performance impact of using biomass power plant ash as a high-performance concrete admixture,this paper conducts a physicochemical analysis of biomass power plant ash,pretreats ash samples,and prepares high-performance concrete specimens with 10%,20%,and 30%dosages for compres‐sive strength testing and chloride ion penetration resistance testing.The results show that using treated biomass power plant ash as an admixture for high-performance concrete,the compressive capacity decrease with the increase of admixture,but overall they meet the strength requirements;Adding bio‐mass power plant ash can improve the resistance of high-performance concrete to chloride ion erosion.
