Municipal solid waste incinerator (MSWI) ash has a similar chemical composition to traditional cement kiln feed components, making it a potentially viable replacement for traditional materials in the absence of deleterious components invariably present in ash. This supposition should be confirmed by lab-scale experimentation prior to full-scale implementation. This study explores lab-scale cement manufacturing using varying replacement percentages of unwashed and water-washed MSWI bottom ash. The use of unwashed MSWI ash as a kiln feed is associated with a considerable decrease in tricalcium silicate content. Each replacement percentage of washed bottom ash incorporation resulted in an approximate tricalcium silicate content of 45%, while unwashed bottom ash specimens had tricalcium silicate contents of approximately 35%. Aluminate concentrations in ash-amended clinkers were considerably higher than reference clinkers, which may require additional gypsum to ensure proper setting. The effects of mineralogical differences were reflected in cement reactivity. Unwashed MSWI ash-amended specimens should be monitored for chloride and alkali content. Results of this study highlight the simultaneous impact of washed and unwashed MSWI bottom ash addition as kiln feed on clinker formation, and the special considerations for clinker production and behavior. The addition of MSWI ash as cement kiln feed is beneficial provided it is washed and appropriately controlled below 8% to reduce deleterious phase composition.

市政固体废物焚化炉（MSWI）的灰分具有与传统水泥窑进料成分相似的化学成分，因此在灰分中不存在有害成分的情况下，它可以潜在地替代传统材料。这种假设应在全面实施之前通过实验室规模的实验加以确认。这项研究探索了使用未清洗和水洗MSWI底灰的不同替代百分比的实验室规模水泥生产。使用未洗涤的MSWI灰作为窑炉进料会大大降低硅酸三钙的含量。洗涤底灰掺入的每个替换百分比导致大约三硅酸钙含量为45％，而未洗涤的底灰试样的硅酸三钙含量大约为35％。灰烬改性熟料中的铝酸盐浓度明显高于参考熟料，这可能需要额外的石膏以确保适当的固化。矿物学差异的影响反映在水泥反应性中。未清洗的MSWI灰分修正样品应进行氯化物和碱含量监测。这项研究的结果突出显示了添加和不添加MSWI底灰作为窑喂料对熟料形成的同时影响，以及熟料生产和行为的特殊考虑。添加MSWI灰作为水泥窑原料是有利的，只要将其洗涤并适当地控制在8％以下以减少有害相组成即可。矿物学差异的影响反映在水泥反应性中。未清洗的MSWI灰分校正样品应进行氯化物和碱含量监测。这项研究的结果突显了添加和未添加MSWI底灰作为窑饲料对熟料形成的同时影响，以及对熟料生产和性能的特殊考虑。添加MSWI灰作为水泥窑原料是有利的，只要将其洗涤并适当地控制在8％以下以减少有害相组成即可。矿物学差异的影响反映在水泥反应性中。未清洗的MSWI灰分修正样品应进行氯化物和碱含量监测。这项研究的结果突出显示了添加和不添加MSWI底灰作为窑喂料对熟料形成的同时影响，以及熟料生产和行为的特殊考虑。添加MSWI灰作为水泥窑原料是有利的，只要将其洗涤并适当地控制在8％以下以减少有害相组成即可。以及熟料生产和行为的特殊考虑。添加MSWI灰作为水泥窑原料是有利的，只要将其洗涤并适当地控制在8％以下以减少有害相组成即可。以及熟料生产和行为的特殊考虑。添加MSWI灰作为水泥窑原料是有利的，只要将其洗涤并适当地控制在8％以下以减少有害相组成即可。
