Curing agent stabilized coal gangue mixture for road base and preparation method of curing agent stabilized coal gangue mixture
The invention discloses a curing agent stabilized coal gangue mixture for a road base and a preparation method of the curing agent stabilized coal gangue mixture. The mixture is composed of 90-95 parts by mass of pretreated coal gangue aggregate and 5-10 parts by mass of a curing agent. The curing agent stabilized coal gangue mixture for the road base prepared by the invention has excellent compressive strength, crack resistance and durability, and is excellent in pavement performance. By adopting a pretreatment mode of combining mechanical strengthening and chemical interface strengthening, on one hand, the strength of the coal gangue granules is effectively improved, and on the other hand, the spontaneous combustion phenomenon possibly occurring in later engineering application can be effectively avoided. The curing agent prepared by the invention can effectively reduce the use amount of cement, can consume a large amount of industrial solid wastes such as coal gangue, fly ash, granulated blast furnace slag powder, gypsum, steel slag and the like, does not generate new pollutants in use, is a low-carbon and environment-friendly solid waste consumption mode, and has good economic and social benefits.
本发明公开了一种用于道路基层的固化剂稳定煤矸石混合料及其制备方法。所述的混合料由90‑95质量份的经过预处理的煤矸石集料与5‑10质量份的固化剂组成。本发明制备的用于道路基层的固化剂稳定煤矸石混合料具有优异的抗压强度、抗裂性能和耐久性，路用性能优良。本发明采用的机械强化与化学界面强化相结合的预处理方式，一方面有效提高煤矸石粒料的强度，另一方面可有效避免后期工程应用中有可能出现的自燃现象。本发明配制的固化剂可有效降低水泥的用量，亦可大量消耗煤矸石、粉煤灰、粒化高炉矿渣粉、石膏、钢渣等大宗工业固废，且在使用中不产生新的污染物，是一种低碳、环保的固废消耗方式，具有良好的经济、社会效益。
