Road base mixture and preparation method thereof
The invention discloses a road base mixture. The road base mixture comprises the following components in parts by weight: 1-2 parts of cement; 2-10 parts of coal ash; 5-15 parts of furnace slag; 30-45parts of gravels; 0.5-1 part of silica fume; and 1-2 parts of excitant. In the road base mixture, the main components of the furnace slag are SiO2 and Al2O3; the main component of the silica fume isSiO2; the furnace slag and the silica fume can react with Ca (OH) 2 generated by hydration reaction of the cement, so that C-A-H and C-S-H gelling substances with stable chemical properties can be generated, so that the mixture has higher strength. On the premise of ensuring that various performance indexes meet the requirements, the utilization rate of the fly ash and the furnace slag is increased as much as possible, cement consumption is reduced, economic benefits are maximized, and various performance indexes are optimized. According to the road base mixture of the invention, the fly ash and the furnace slag are applied to road infrastructure construction, so that the pollution to the surrounding environment caused by accumulation of a large amount of industrial wastes is reduced, theconsumption of natural gravels can be reduced, and the purposes of changing wastes into valuables and realizing sustainable development are achieved.
本发明公开了一种道路基层混合料，包括以下重量份组分：水泥1～2份，粉煤灰2～10份，炉渣5～15份，碎石30～45份，硅灰0.5～1份，激发剂1～2份。本发明的道路基层混合料中，炉渣主要成分是SiO和AlO，硅灰的主要成分是SiO，它们能与水泥水化反应产生的Ca(OH)发生反应，生成化学性质稳定的C‑A‑H和C‑S‑H胶凝物质，使得混合料具有较高的强度。本发明在保证各项性能指标符合要求的前提下，尽可能提高粉煤灰和炉渣的利用率，降低水泥用量，使其经济效益最大化，并且使得各项性能指标达到最优化。本发明将粉煤灰和炉渣应用于道路基础建设中，不仅减少工业废料大量堆积对周边环境的污染，还可以减少对天然碎石的消耗，达到了变废为宝，可持续发展的目的。
