Grouting material and preparation method thereof
The invention relates to a grouting material and a preparation method thereof, and belongs to the technical field of building materials. The grouting material is prepared by compounding and stirring a phosphorus-magnesium-based cementing material, aggregate, steel fibers, a functional additive and water according to the mass ratio of 1: (0.5-1.5): (0.06-0.16): (0.03-0.1): (0.05-0.15), the grouting material realizes super early strength and super strength while realizing ultralow water demand, and also has good system stability; compared with a traditional steel fiber grouting material, the steel fiber grouting material has higher compression resistance and deformation resistance, and has no necking phenomenon under bending or tensile deformation; the grouting material has good ductility, the ductility can reach 2-10%, the compressive strength can reach 100 MPa or above within one day, the volume shrinkage rate within 0.02% within 28 days, and the grouting material is suitable for rapid first-aid repair construction in engineering.
本发明涉及一种灌浆料及其制备方法，属于建筑材料技术领域。所述灌浆料由磷镁基胶凝材料、骨料、钢纤维、功能助剂和水按照质量比＝1:0.5～1.5:0.06～0.16:0.03～0.1:0.05～0.15复合搅拌而成；所述灌浆料在实现超低需水量的同时，实现超早强、超高强，还具有良好的体系稳定性；比传统钢纤维灌浆料具有更高的抗压性能和抗变形性能，在受弯或拉伸变形下无颈缩现象；所述灌浆料具有良好的延伸率，延伸率可达2％～10％，1天即可实现抗压强度100MPa以上，28天体积收缩率在0.02％以内，适用于工程中的急速快速抢修施工。
