摘　　要：进行了飞灰单掺及复掺矿物掺合料的混凝土试验,对不同配比混凝土进行了微观形貌、工作性能、力学性能、耐久性能、重金属浸出量的研究。结果表明,单掺飞灰的混凝土具有良好的力学性能及耐久性能,且重金属的浸出量未超过国家标准,适当掺量的飞灰可直接应用于普通建筑混凝土结构。The experiments of adding municipal solid waste incineration（MSWI） fly ash and complex adding mineral admixtures into concrete are carried out.Through the micro-morphology,operating performance,mechanical properties,durability properties and leaching toxicity test of heavy metals,the concrete with different mix proportions are researched.The experimental results indicate that the concrete mixed with fly ash has good mechanical properties and durability properties,and its leaching toxicity of heavy metal also complies with the national standards,which means that suitable mixing quantity of MSWI fly ash can directly apply in the ordinary construction concrete structure.
