摘　　要：采用水洗预处理垃圾飞灰替代部分原料制备水泥,考察了配比量和养护时间对其力学性能的影响。当水泥胶砂中掺入水洗预处理垃圾飞灰时,其抗压抗折强度均有一定程度的下降。当养护时间达到28 d时,水洗预处理垃圾飞灰掺量为10%的试件抗压抗折强度达到最高。生产的制品浸出毒性都达到浸出毒性国家标准,并且远低于浸出限值,符合环境安全要求。Washing pretreatment garbage fly ash was uesd to replace part of the raw materials to prepare cement,and the influence of the proportion and curing time on its mechanical properties was investigated.When cement mortar was mixed with water-washed pre-treated garbage fly ash,its compressive and flexural strength will decrease to a certain extent.When the curing time reaches 28 days,the compressive and flexural strength of the sample with 10%of the pre-treated garbage fly ash content reached the highest.The leaching toxicity of the produced products has reached the national standards for leaching toxicity,and was far below the leaching limit,which meets the environmental safety requirements.
