Cement fluidized bed combustion ash goaf grouting filling material as well as preparation method and application thereof
The invention provides a cement fluidized bed combustion ash goaf grouting filling material as well as a preparation method and application thereof, and belongs to the technical field of road engineering materials. The cement fluidized bed combustion ash goaf grouting filling material comprises the following components in parts by mass: 5-15 parts of cement, 85-95 parts of fluidized bed combustion ash, 1-3 parts of a viscosity reducer, 0.1-0.3 part of an accelerator, 2-7 parts of an expansion regulator and 75-90 parts of water. The fluidity, the setting time, the strength and the expansion and shrinkage of the grouting filling material can be adjusted and controlled, the technical requirements of different goaf projects are met, and the performance is greatly superior to that of a traditional grouting filling material. Besides, the mixing amount of the solid waste and fluidized bed combustion ash reaches 85% or above, the cost is lower than 50 yuan/m < 3 >, the cost is reduced by 50% or above compared with that of a traditional cement and fly ash grouting filling material, 600kg of solid waste and fluidized bed combustion ash can be consumed per square meter, and social and economic benefits are remarkable. The method can be used for filling underlying goaf of roads and railways, and is simple to operate and easy to implement.
本发明提供了一种水泥固硫灰采空区注浆充填材料及制备方法与应用，属于道路工程材料技术领域。本发明水泥固硫灰采空区注浆充填材料按以下质量份组成：水泥5～15份、固硫灰85～95份、降粘剂1～3份、速凝剂0.1～0.3份、膨胀调整剂2～7份，水75～90份。本发明还可实现注浆充填材料的流动性、凝结时间、强度、胀缩性可调可控，满足不同采空区工程的技术要求，性能大幅优于传统注浆充填材料。另外，本发明固废固硫灰掺量达到85％以上，成本低于50元/m3，较传统水泥粉煤灰注浆充填材料降低成本50％以上，而且每方可消纳固废固硫灰600kg，社会经济效益显著。可用于公路、铁路下伏采空区充填，操作简便，易于实施。
