Red-layer soft rock roadbed mixture based on potassium fixation and strong cementation synergistic effect and preparation method of red-layer soft rock roadbed mixture
The invention discloses a preparation method of a red-layer soft rock roadbed mixture based on potassium immobilization and strong cementation synergistic effect. The red-layer soft rock roadbed mixture comprises the following raw materials: 100 parts of red-layer soft rock and 6-9 parts of a modifier, the modifier comprises a first modifier and a second modifier; the first modifier is composed of potassium humate and potassium formate according to the mass ratio of (2-4): 1; the second modifier is prepared from the following components in parts by mass: 35 to 45 parts of mineral powder, 30 to 40 parts of tricalcium silicate, 2 to 5 parts of calcium aluminate, 12 to 15 parts of calcium sulfate and 8 to 12 parts of anhydrous magnesium sulfate. The red-layer soft rock roadbed mixture prepared by the invention has relatively good strength and water stability at the same time, solves the engineering application problems that the red-layer soft rock roadbed mixture is low in strength and easy to swell and disintegrate when meeting water, is suitable for highway construction in a red-layer soft rock region, achieves the purpose of resource utilization of red-layer soft rock, and has relatively good environmental protection and economic benefits.
本发明公开了一种基于钾固定和强胶结协同作用的红层软岩路基混合料的制备方法，生产原料包括：红层软岩100份，改性剂6～9份；改性剂包括第一改性剂和第二改性剂；第一改性剂由腐殖酸钾和甲酸钾按照质量比2～4:1的比例组成；第二改性剂由如下质量份数比例的各组分组成：矿粉35～45份，硅酸三钙30～40份，铝酸钙2～5份，硫酸钙12～15份，无水硫酸镁8～12份。本发明制备的红层软岩路基混合料同时具有较好强度和水稳定性，解决了红层软岩路基混合料强度低、遇水易膨胀崩解的工程应用问题，适用于红层软岩地区公路建设，达到红层软岩资源化利用的目的，具有较好的环保和经济效益。
