Solid waste feldspar powder highway base material and preparation method thereof
The invention belongs to the technical field of highway engineering, and discloses a solid waste feldspar powder highway base material and a preparation method thereof. The highway base material is prepared from the following raw materials in parts by mass: 60-90 parts of feldspar powder, 0-23 parts of gravel and 7-10 parts of a composite curing agent, the composite curing agent comprises a diagenesis agent, a mineral admixture, a surfactant and an early strength agent, wherein the mass ratio of the diagenesis agent to the mineral admixture to the surfactant to the early strength agent is (15-30): (50-70): (5-10): (10-20). The problem that the comprehensive utilization rate of traditional feldspar powder is low is solved, preparation of the highway base material with the large-dosage feldspar powder is achieved, the dosage of the feldspar powder is increased to 60%-90%, the application amount of the feldspar powder is achieved, the strength of a feldspar powder base is improved, the anti-scouring capacity of the feldspar powder base is enhanced, and the durability of the base is improved; the large-scale consumption of industrial solid waste is facilitated, and meanwhile, the use amount of gravel materials in highway engineering is reduced.
本发明属公路工程技术领域，公开了一种固废长石粉的公路基层材料及其制备方法。所述公路基层材料由如下质量份的原料组成：长石粉60～90份，碎石0～23份，复合固化剂7～10份；所述复合固化剂包括成岩剂、矿物掺和料、表面活性剂和早强剂，其中成岩剂、矿物掺和料、表面活性剂和早强剂的质量比为15～30：50～70：5～10：10～20。本发明克服了传统长石粉综合利用率低的问题，实现大掺量长石粉公路基层材料的制备，将长石粉的掺量提高到60～90％，实现长石粉的应用量，提高长石粉基层的强度，增强长石粉基层的抗冲刷能力，提升基层的耐久性，有利于大规模消纳工业固废，同时减少公路工程中砂石料的用量。
