Geopolymer cementing material for pavement base based on multielement solid waste synergy and preparation method of geopolymer cementing material
The invention discloses a geopolymer cementing material for pavement base based on multielement solid waste synergy and a preparation method of the geopolymer cementing material. The geopolymer cementing material is mainly characterized in that fly ash, slag, carbide slag and desulfurized gypsum are used as main materials, the characteristics of various solid wastes are fully played, and the geopolymer cementing material is prepared on the basis of the principle of the geopolymer cementing material by utilizing the synergistic enhancement effect of the solid wastes. Through three main procedures of drying, grinding and secondary uniform mixing, the geopolymer cementing material special for the pavement base is prepared, wherein various performance indexes of the geopolymer cementing material meet the requirements of JT/T 994-2015 Cement for Highway Engineering Pavement Base Stability. Compared with the traditional cement-stabilized pavement base material, the dry shrinkage of the cement-stabilized pavement base material is greatly improved, and the crack hazard of the pavement caused by the dry shrinkage of the base is obviously reduced. Meanwhile, a large number of road building materials can be saved, waste is fully utilized, energy is saved, environmental pollution is reduced, resources are saved, the environment is protected, the road quality is improved, and the green traffic development concept is met.
本发明公开了一种基于多元固废协同的路面基层用地聚物胶凝材料及其制备方法，其主要特征是以粉煤灰、矿渣、电石渣、脱硫石膏为主要，充分发挥各种固废特性，利用其协同增强作用，基于地聚物胶凝材料原理，通过烘干、粉磨、二次混匀等三段主要工序，制备出各项性能指标符合JT/T 994‑2015《公路工程路面基层稳定用水泥》要求的路面基层专用地聚物胶凝材料。与传统的水泥稳定路面基层材料相比，其干缩性得到极大的改善，显著的减少路面由于基层干缩造成的裂缝危害。同时该发明不仅可以节约大量的筑路材料，充分利用废弃物，还有利于节约能源，降低环境污染，达到节约资源、保护环境、提高公路质量，符合绿色交通发展理念。
