Nano aluminum oxide superfine cement-based composite grouting full-length anchoring material
The invention relates to the technical field of grouting materials, in particular to a nanometer aluminum oxide superfine cement-based composite grouting full-length anchoring material which is used for solving the problems that a chemical grouting material is high in cost, low in strength and poor in durability, meanwhile, large pollution is caused to the environment, a large amount of energy needs to be consumed for preparation of an ordinary Portland cement grouting material, and the cost is low. The problems that in the prior art, common cement is large in particle size, large in carbon dioxide emission amount and capable of generating a large amount of construction waste, common cement is large in particle size and has the defects of many coarse particles, poor slurry stability, incapability of being injected into tiny cracks and the like, and the two grouting materials cannot completely meet engineering requirements are solved. The prepared nanometer aluminum oxide superfine cement-based composite grouting full-length anchoring material serves as an anchoring agent, in a full-length anchoring surrounding rock system, the bearing capacity of an overall component is obviously superior to that of a common cement-based grouting material under the same condition, and meanwhile the enhanced deformation coordination capacity and good durability are achieved.
本发明涉及注浆材料技术领域，具体涉及纳米氧化铝超细水泥基复合注浆全长锚固材料，用于解决化学注浆材料成本较高、强度较低、耐久性较差，同时对环境造成较大污染，普通硅酸盐水泥注浆材料制备需要消耗大量能源，二氧化碳排放量巨大，同时会产生大量建筑垃圾，此外，普通水泥粒径较大，存在粗颗粒多、浆液稳定性差、无法注入微小裂隙等缺点，这两种注浆材料均无法完全满足工程需求的问题；本发明制备的纳米氧化铝超细水泥基复合注浆全长锚固材料作为锚固剂在全长锚固围岩体系中整体构件承载力明显优于同等条件下普通水泥基注浆材料，同时具有增强的协调变形能力和好的耐久性。
