Carbide slag fly ash stabilized soil material for roads and preparation method thereof
The invention discloses a carbide slag fly ash stabilized soil material for roads and a preparation method thereof, the carbide slag fly ash stabilized soil material comprises the following components by mass percentage: 4%-12% of carbide slag, 8%-17% of fly ash, 77%-85% of dry soil, 0.1% of polypropylene fiber and 0.004% of an active activator. Crystalline crystals such as hydrated calcium silicate, hydrated calcium aluminate, ettringite and the like are generated through a pozzolanic reaction of the carbide slag and the fly ash cementing material, and meanwhile, the tensile strength of the stabilized soil is improved by doping the polypropylene fibers. A filling material is provided for a road base and a subbase, the problems of accumulation and storage of the carbide slag and the fly ash, insufficient utilization rate, soil and environment pollution and the like can be effectively solved, the industrial waste residues are reasonably recycled and secondarily developed, and the material is very beneficial to the development of the country, society and enterprises no matter from the perspective of social benefit, environmental benefit and economic benefit, and is also beneficial to the sustainable development and utilization of natural resources.
本发明公开的一种用于道路的电石渣粉煤灰稳定土材料及其制备方法，按质量百分比，包括4％～12％的电石渣，8％～17％的粉煤灰，77％～85％的干土，0.1％的聚丙烯纤维和0.004％活性激发剂。通过电石渣与粉煤灰胶结料的火山灰反应，生成水化硅酸钙、水化铝酸钙及钙矾石等结晶体，同时，聚丙烯纤维的掺入提高了稳定土拉韧性。不仅为道路基层、底基层提供了一种填筑材料，还能够有效的解决电石渣及粉煤灰堆积存放、利用率不足及土质和环境污染等问题，将工业废渣合理的资源化二次开发，无论从社会效益、环境效益还是经济效益方面分析，都是非常有利于国家、社会和企业发展的事情，同时，还有利于自然资源的可持续开发利用。
