Cement-stabilized red sandstone base material for compensating dry shrinkage performance and preparation method of cement-stabilized red sandstone base material
The invention relates to a cement-stabilized red sandstone base material which takes red sandstone as aggregate, and cement, calcined phosphogypsum, slag and carbide slag are used for compensating drying shrinkage of a cement-stabilized base, the cement-stabilized red sandstone base material comprises the aggregate and an inorganic binder, and the aggregate comprises and only comprises graded red sandstone; the inorganic binder comprises the following components in parts by mass: 94 parts of aggregate and 6 parts of a mixture of cement, calcined phosphogypsum, carbide slag and slag; in the inorganic binder, the cement accounts for 3.3-3.72 parts, and the slag accounts for 1.8 parts; the calcined ardealite and the carbide slag account for 0.48-0.9 part in total, and the weight ratio of the carbide slag to the calcined ardealite is (0.6-2): 1. The material is used as a pavement base by compensating the dry shrinkage performance, and can eliminate the dry shrinkage of the pavement and improve the durability of the pavement base.
本发明涉及一种以红砂岩为骨料，水泥、煅烧磷石膏、矿渣以及电石渣补偿水泥稳定基层干燥收缩的水泥稳定红砂岩基层材料，包括骨料和无机结合料，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、煅烧磷石膏、电石渣和矿渣混合物，其中，各成分质量份数为骨料94份，无机结合料6份；无机结合料中，水泥占3.3‑3.72份，矿渣占1.8份；煅烧磷石膏和电石渣共占0.48‑0.9份，其中电石渣与煅烧磷石膏的重量比为(0.6‑2)：1。本发明的材料经补偿干缩性能，用作路面基层，能够消除路面干燥收缩，提高道路基层耐久性。
