Ultra-high-performance grouting material for prefabricated part splicing and preparation method thereof
The invention relates to an ultrahigh-performance grouting material for splicing prefabricated parts and a preparation method thereof, the ultrahigh-performance grouting material comprises a premix, and the premix comprises the following raw materials: 25-35 parts of cement, 1-5 parts of fly ash, 3-10 parts of microbeads, 3-10 parts of silica fume, 1-4 parts of a nano material, 45-60 parts of aggregate, 1-4 parts of a water reducing agent and 0.5-3 parts of a composite additive, the particles with the particle size of 2.36-1.18 mm account for 15-25%, the particles with the particle size of 1.18-06 mm account for 25-35%, the particles with the particle size of 0.6-0.3 mm account for 25-35%, the particles with the particle size of 0.3-0.15 mm account for 5-15%, and the particles with the particle size smaller than 0.15 mm account for 5-15%; the composite additive is a combination of an expanding agent, a water-retaining agent, a viscosity reducer and a defoaming agent. On the basis that steel fibers are not used, based on the graded aggregate in a specific proportion, the prepared grouting material can be matched with a high-performance concrete member in strength and consistent with durability by combining the grading design of a nano material and the aggregate and regulation and control of other components, construction operation is convenient, and the grouting material is used for splicing prefabricated members and has the advantages that the construction cost is reduced; and integrated safe splicing and mounting of the prefabricated parts can be guaranteed.
本发明涉及一种预制构件拼接用超高性能灌浆料及其制备方法，包括预混料，预混料的原料配方包括：水泥25～35份、粉煤灰1～5份、微珠3～10份、硅灰3～10份、纳米材料1～4份、骨料45～60份、减水剂1～4份和复合添加剂0.5～3份，骨料中，粒径2.36mm‑1.18mm的占15‑25％、粒径1.18mm‑06mm的占25‑35％、粒径0.6mm‑0.3mm的占25‑35％、粒径0.3mm‑0.15mm的占5‑15％、粒径小于0.15mm的占5‑15％；复合添加剂为膨胀剂、保水剂、降粘剂和消泡剂的组合。本发明在不使用钢纤维的基础上，基于特定比例的级配骨料，结合纳米材料、骨料级配设计及其他各组分的调控，制备的灌浆料能够与高性能混凝土构件强度匹配、耐久性相符、施工操作便利，用于预制构件拼接用，能够保障预制构件的一体化安全拼接与安装。
