High-curing backfill material for sealing building slag pores by using silt as well as preparation method and application of high-curing backfill material
The invention provides a high-curing backfill material for sealing building slag pores by silt as well as a preparation method and application of the high-curing backfill material. The high-curing backfill material is prepared from the following components in parts by weight: 37 to 59 parts of silt, 2 to 6 parts of layered illite bentonite, 13 to 33 parts of building slag, 5 to 10 parts of terminated isocyanate group curing agent and 19 to 27 parts of water. According to the invention, the building slag with high strength and a certain particle size is used as a main material, the micro-swelled silt is used for making up the defects of more pores and easy water absorption of the building slag, and meanwhile, the end-sealed isocyanate curing agent is used as a cementing material for curing, so that the high-curing backfill material with the pores of the building slag sealed by the silt is obtained; the obtained high-curing backfill material has high flowability, self-compaction performance and high curing performance, not only can meet the service requirements of backfill materials for high-load roads and airport flying areas, but also recycles waste construction waste, and has high economic value and social and environmental benefits.
本发明提供一种粉土封闭建渣孔隙的高固化回填材料及其制备方法与应用。该高固化回填材料包括如下重量份的组分:粉土37~59份、层状伊利石膨润土2~6份、建渣13~33份、端封异氰酸酯基固化剂5~10份以及水19~27份。本发明,采用强度较高且具有一定粒径的建渣作为主要材料,并以微膨润的粉土弥补建渣孔隙多、易吸水的缺陷,同时用端封异氰酸酯固化剂作为胶凝材料进行固化,从而得到粉土封闭建渣孔隙的高固化回填材料,所得高固化回填材料具有高流动性、自密实性和高固化性能,不但能够满足高荷载道路以及机场飞行区回填材料的服役要求,而且循环利用了废弃的建筑垃圾,具有较高的经济价值以及社会与环境效益。
