Road roadbed material based on construction waste and preparation method thereof
The invention relates to the technical field of road engineering materials, in particular to a road roadbed material based on construction waste and a preparation method of the road roadbed material. The road roadbed material comprises the following raw materials in parts by weight: 60-70 parts of gravel, 40-50 parts of sand, 1-2 parts of muck, 60-70 parts of a cementing material and 15-35 parts of water, wherein the cementing material comprises construction waste, gypsum, water and a composite exciting agent. According to the invention, the activity of the 0-300 [mu] m construction waste is excited by using the composite activator, then the construction waste is prepared into the cementing material again, and the strength and hardness of the material are improved by regulating and controlling the ratio of various substances in the cementing material, so that the requirements on the roadbed are met; meanwhile, gypsum is added into a gelling system, so that the strength of the roadbed material can be enhanced, the digestion effect of lime in the system is inhibited, volume expansion is limited, and the freezing resistance of a foundation is improved.
本发明涉及道路工程材料技术领域，具体涉及一种基于建筑垃圾的道路路基材料及其制备方法。道路路基材料，其原料按重量份包括：碎石60～70份、砂40～50份、渣土1～2份、胶凝材料60～70份和水15～35份；其中，胶凝材料包括建筑垃圾、石膏、水和复合激发剂。本发明中通过采用复合激发剂激发0～300μm的建筑垃圾的活性，进而将其重新制备成胶凝材料，通过调控胶凝材料中各个物质的配比，提高了材料的强度和硬度，满足对路基的要求；同时，在胶凝体系中加入石膏可以增强路基材料的强度，抑制体系中石灰的消化作用、限制体积膨胀以及提高地基的抗冻性等。
