Rapid pavement repairing mortar compounded with magnesium cement and alkali-activated slag and preparation method of rapid pavement repairing mortar
The invention belongs to the technical field of engineering building materials, and particularly relates to rapid pavement repairing mortar compounded with magnesium cement and alkali-activated slag and a preparation method of the rapid pavement repairing mortar. The rapid pavement repairing mortar comprises dead burned magnesium oxide, dipotassium phosphate, disodium hydrogen phosphate, household garbage incineration slag, nano colloidal silicon dioxide, fine aggregate, water, nano cellulose and a water reducing agent. A hydration intermediate product of a magnesium phosphate cementing material reacts with nano colloidal silicon dioxide to generate potassium silicate and sodium silicate, the household garbage incineration slag is excited, and high-water-resistance C-A-S-H gel is generated. The household garbage incineration slag is effectively utilized, the green and environment-friendly development concept is practiced, and the water resistance of the magnesium phosphate cementing material is improved. Similarly, due to the addition of the nanocellulose, the volume stability of the mortar is improved, and the impermeability of the mortar is also remarkably improved. Therefore, the method has positive significance in preparation and application of the magnesium phosphate cementing material in the field of rapid pavement repair.
本发明属于工程建筑材料技术领域，具体涉及一种复合镁水泥与碱激发炉渣的路面快速修补砂浆及其制备方法；其中，路面快速修补砂浆包括：重烧氧化镁、磷酸氢二钾、磷酸氢二钠、生活垃圾焚烧炉渣、纳米胶态二氧化硅、细骨料、水、纳米纤维素和减水剂。本发明利用磷酸镁胶凝材料的水化中间产物与纳米胶态二氧化硅反应生成硅酸钾和硅酸钠，激发生活垃圾焚烧炉渣，生成了高耐水性的C‑A‑S‑H凝胶。这不仅有效地利用了生活垃圾焚烧炉渣，践行绿色环保发展理念，且提高磷酸镁胶凝材料耐水性能。同样，由于加入了纳米纤维素，不仅提高砂浆的体积稳定性，对其抗渗性能也有显著的提升。因此，对实现磷酸镁胶凝材料在路面快速修补领域的制备与运用具有积极意义。
