Application of household garbage incineration fly ash composite admixture in cement stabilized macadam mixture
The invention relates to application of a household garbage incineration fly ash composite admixture in a cement stabilized macadam mixture, and belongs to the technical field of crossing of environmental engineering and highway engineering. According to the invention, the household garbage incineration fly ash is used as a stable material; the cement/incineration fly ash stabilized macadam mixture is mainly prepared by blending domestic waste incineration fly ash with an active mixed material and an excitant to form a composite admixture and then forming a composite cementing system togetherwith cement to stabilize graded macadam mineral aggregate; and the cement/incineration fly ash stabilized macadam mixture can be used in highway pavement base layers and subbase layers. According to the invention, component complementation and activity excitation effects in the composite admixture are utilized; the potential gelatinization activity of the incineration fly ash is released to the greatest extent to provide a high-activity cementing effect; meanwhile, heavy metal components contained in the incineration fly ash are stably solidified through the solidification effect of the composite cementing system, so that the cement/incineration fly ash stabilized macadam mixture with good performance is prepared, the recycling and harmless disposal target of the household garbage incineration fly ash is achieved, the use amount of cementing materials is reduced for highway engineering, and the engineering cost is reduced.
本发明涉及生活垃圾焚烧飞灰复合掺合料在水泥稳定碎石混合料中的应用，属于环境工程与公路工程交叉技术领域。本发明将生活垃圾焚烧飞灰作为稳定材料使用，主要是将生活垃圾焚烧飞灰先与活性混合材料、激发剂共混形成复合掺合料，然后与水泥形成复合胶凝体系共同稳定级配碎石矿料，制备得到水泥/焚烧飞灰稳定碎石混合料，可以用于公路路面基层、底基层中。本发明利用复合掺合料中组分互补与活性激发作用，大限度释放焚烧飞灰潜在的胶凝活性来提供高活性胶结作用，同时利用复合胶凝体系的固结作用稳定固化焚烧飞灰中含有的重金属成分，从而制备性能良好的水泥/焚烧飞灰稳定碎石混合料，并达到生活垃圾焚烧飞灰的资源化、无害化处置目标，以及为公路工程节省胶结料用量、节约工程造价。
