Lime deironing copper tailing stabilized sea sand semi-rigid base layer and preparation method thereof
The invention belongs to the technical field of building materials, and particularly discloses a lime iron removal copper tailing stabilized sea sand semi-rigid base layer which is prepared by uniformly mixing the following components in percentage by mass: 75.5-89.5% of desalted sea sand, 7.5-17.5% of iron extraction copper tailings and 3-7% of lime. The invention further discloses a preparationmethod of the lime iron removal copper tailing stabilized sea sand mixture. The lime deironing copper tailing stabilized sea sand semi-rigid base base layer prepared by the method has the characteristics of convenience in material taking, energy conservation and environmental protection, and is a novel building material; the material can utilize a large amount of copper tailings and sea sand, cansolve the problems of environmental protection and land occupation caused by the copper tailings and relieve increasingly scarce mineral admixtures and sand resources, and has important economic significance and environmental protection significance. The unconfined compressive strength of the lime deironing copper tailing stabilized sea sand semi-rigid base layer prepared by the method meets the standard requirements, the manufacturing cost of the semi-rigid base layer can be greatly reduced, and the production cost is greatly reduced.
本发明属于建筑材料技术领域，具体公开了一种石灰除铁铜尾矿稳定海砂半刚性基层，其包括混合均匀的具有以下质量百分含量的各组分：75.5%～89.5%的淡化海砂、7.5%～17.5%的提铁铜尾矿、3%～7%的石灰。本发明还公开了上述石灰除铁铜尾矿稳定海砂混合料的制备方法。本发明制备的石灰除铁铜尾矿稳定海砂半刚性基层具有取材便利、节能环保的特点，是一种新型的建筑材料；该材料可以大量利用铜尾矿、海砂，可解决铜尾矿造成的环保及占有土地问题以及缓解日益短缺的矿物掺合料、砂资源，具有重要的经济意义和环保意义。本发明制备得到的石灰除铁铜尾矿稳定海砂半刚性基层的无侧限抗压强度满足规范要求，且能大幅度降低半刚性基层的造价，大大降低了生产成本。
