Cement soil stabilized molybdenum tailing mixture and application thereof as road structure subbase
The invention belongs to the technical field of road building materials, and particularly relates to a cement-soil-stabilized molybdenum tailing mixture and application of the cement-soil-stabilized molybdenum tailing mixture as a subbase of a road structure, the cement-soil-stabilized molybdenum tailing mixture comprises the following raw materials: cement, clay and molybdenum tailings, according to the weight ratio, the mixing ratio of the clay to the molybdenum tailings is (20-50): (50-80), and the mixing ratio of the clay to the molybdenum tailings is (20-50): (50-80). The weight of the doped cement is 5-11% of the sum of the weights of the clay and the molybdenum tailings, and the mixture can be used as a subbase of a road structure to be constructed by using a road mixing method. The molybdenum tailings are used for replacing part of soil in the cement stabilized soil, the formed cement soil stabilized molybdenum tailing mixture has good dry shrinkage resistance and temperature shrinkage resistance, and the strength requirements of light, medium and heavy traffic grade pavement structure subbase layers can be met according to different mixing ratios; the defects that the bearing capacity and durability of the pavement structure are reduced due to shrinkage cracking caused by temperature and humidity changes of the cement stabilized soil subbase layer are overcome, and resource utilization of industrial solid waste is achieved.
本发明属于道路建筑材料技术领域，具体涉及一种水泥土稳定钼尾矿混合料及其作为道路结构底基层的应用，该水泥土稳定钼尾矿混合料原材料包括水泥、黏土和钼尾矿，按照重量比，黏土与钼尾矿配合比例为(20~50):(50~80)，水泥的掺加重量为黏土与钼尾矿重量之和的5~11%，该混合料可作为道路结构底基层使用路拌法施工。本发明用钼尾矿代替水泥稳定土中部分土，组成的水泥土稳定钼尾矿混合料具有良好的抗干缩和抗温缩性能，根据不同配合比可满足轻与中等、重交通等级路面结构底基层强度要求，解决了水泥稳定土底基层因温度及湿度变化引起收缩开裂导致路面结构承载能力及耐久性能衰减等缺陷，实现了工业固体废弃物的资源化利用。
