Reinforced cement-stabilized red sandstone base material and preparation method of base test piece
The cement-stabilized red sandstone base material comprises aggregate and an inorganic binder, and is characterized in that the aggregate comprises and only comprises graded red sandstone, the inorganic binder comprises cement, limestone powder and a red sandstone powder mixture, and the mass part of each component is 90-100 parts; 4.7 to 5.5 parts of cement; the total weight of the red sandstone powder and the limestone powder is 0.5-1 part; wherein the ratio of the red sandstone powder to the limestone powder is (1-3): 1. The invention further relates to a method for preparing the base layer test piece. The material has the advantages of resource expansion, cost reduction, reduction of carbon dioxide emission, similar pavement performance with a common cement stable base layer, realization of sustainable development of modernization of road traffic, low hydration heat release, good durability, rapid unconfined compressive strength increase in the later stage of hydration, and good comprehensive performance. Finally, the unconfined compressive strength meeting the requirements of the base material can be obtained, and the adverse effect of the soft aggregate is eliminated.
涉及一种水泥稳定红砂岩基层材料，包括骨料和无机结合料，其特征在于，所述骨料包括且仅包括级配红砂岩，所述无机结合料包括水泥、石灰石粉和红砂岩粉混合物，其中，各成分质量份数为骨料90‑100份；水泥4.7‑5.5份；红砂岩粉和石灰石粉共计0.5～1份；其中红砂岩粉与石灰石粉的配比为(1～3)：1。以及涉及一种制备基层试件的方法。本材料具有扩大资源、降低成本以及减少二氧化碳排放，同时具备与普通水泥稳定基层相近的路用性能，实现公路交通现代化的可持续发展，此外具有较低的水化放热量以及较好的耐久性能，并且在水化后期无侧限抗压强度增长快速，最终可获得符合基层材料要求的无侧限抗压强度，消除软弱骨料的不利影响。
