Grouting material for low-negative-temperature construction as well as preparation method and application of grouting material
The invention relates to the technical field of cement-based building materials, in particular to a grouting material for low-negative-temperature construction and a preparation method and application of the grouting material. Ordinary Portland cement is adopted as a main cementing material, amorphous calcium aluminate minerals and anhydrite are matched to serve as rapid hardening agents, and superfine mineral admixtures and synergists are added to serve as active components; the opening time of the grouting material is guaranteed while the low-negative-temperature mechanical strength of the grouting material is jointly improved, the utilization rate of industrial solid waste is increased, the product cost is reduced, and the grouting construction effect is adjusted by adding the water reducing agent, the retarder, the anti-dispersing agent and the thickening agent.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种低负温施工用注浆材料及其制备方法与应用，通过采用普通硅酸盐水泥作为主要胶凝材料，配合非晶态铝酸钙矿物与硬石膏作为快硬剂，添加超细矿物掺合料和增效剂作为活性组分，在共同提高注浆材料低负温力学强度的同时保证其开放时间，并提高工业固废的利用率，降低产品成本，添加减水剂、缓凝剂、抗分散剂和增稠剂调节注浆施工效果。
