摘 要：以硫铝酸盐水泥和脱硫石油焦灰为复合胶凝材料，基于双氧水发泡工艺制备发泡保温材料。研究了水胶比和发泡剂用量对脱硫石油焦灰—硫铝酸盐水泥发泡体系抗压强度和干表观密度的影响。试验结果表明，水胶比相同时，发泡水泥的干表观密度和抗压强度均随发泡剂用量增加而降低，而抗压强度在发泡剂增加到一定程度时趋于稳定；发泡剂用量相同时，干表观密度随水胶比增加而先增加后降低，抗压强度随水胶比增加总体呈上升趋势。其中当水胶比较低时，试块强度增长较快；当水胶比较高时，试块强度趋于稳定。 Abstract: Using sulphoaluminate cement and desulfurization of petroleum coke ash as composite cementitious materials, foaming thermal insulation material is prepared by hydrogen peroxide foam system. The influence of water-binder ratio and amout of foaming agent on compressive strength and dry bulk density of petroleum coke ash-sulphoaluminate cement foaming system is studied. The experiment results show that, at the same water binder ratio, while the amount of foaming agent increases, dry bulk density of foam cement and compressive strength decreases. The compressive strength of foam cement tends to be stable in some certain degree with the increasing of foaming agent; as the same amount of foaming agent, dry bulk density increases at first then decreases. With the increasing the water-binder ratio, the compressive strength increases in general. When the water binder ratio is relatively low, strength of block increases rapidly; while the water binder ratio is high, the strength of block tends to be stable.

摘 要：随着城市生活垃圾焚烧处理方式的不断推广，焚烧飞灰的产生量也不断增加。由于垃圾焚烧飞灰中富含有害重金属，属于危险废物，必须进行无害化处理。应用常规的工艺方法，用飞灰取代部分水泥制备砌筑砂浆；研究了飞灰对砂浆拌合物稠度、凝结时间等基本性能以及砂浆的力学性能和重金属浸出规律的影响，并进行了微观分析。试验结果表明，虽然飞灰会损失砂浆部分强度，但是砂浆能大幅度地减少重金属的浸出量；水泥对飞灰中重金属的固化效果良好，同时以飞灰作为辅助材料制备砂浆可以作为飞灰资源化利用的有效途径。 Abstract: With the further promotion of municipal solid waste incineration (MSWI) method, the output of MSWI fly ash is increasing. Because fly ash contains harmful heavy metal waste which belongs to the hazardous waste, it must be harmless treatment. The partial cement is replaced by MSWI fly ash for the preparation of masonry mortar by using the conventional process. The influence of fly ash on the performance of mortar mixture consistency, setting time, the mechanical properties and heavy metal leaching rule of cement mortar, and the micro analysis are studied. The results show that although MSWI fly ash can lose the partial strength of mortar, but the mortar can significantly reduce the leaching amount of heavy metals. Heavy metals in fly ash are excellently solidified by cement, and preparation of mortar with MSWI fly ash as a supplementary material can be used as an effective way of resource utilization of MSWI fly ash.
