High-performance sleeve grouting material for steel bar connection and preparation method thereof
The invention belongs to the technical field of building materials, and provides a high-performance sleeve grouting material for steel bar connection and a preparation method thereof. The high-performance sleeve grouting material for steel bar connection is composed of Portland cement, sulphoaluminate cement, gypsum, titanium extraction tailings, a water retaining agent, a water reducing agent, anantifoaming agent, a PEA expanding agent and graded quartz sand, during preparation, the Portland cement, the sulphoaluminate cement, the gypsum, the titanium extraction tailings and the graded quartz sand are mixed together, and then the rest raw materials are added and mixed together. The grouting material has the advantages of excellent physical and mechanical properties, excellent working performance, easy grouting, no bleeding, good fluidity, small fluidity time-dependent loss, long operable time, fast early strength development, high strength, good volume stability and no shrinkage cracking problem. The preparation method is simple, is suitable for sleeve grouting engineering for steel bar connection of fabricated building components, can have high mechanical properties in a short time, is excellent in long-term use efficiency, and ensures the engineering quality and the service life.
本发明属建筑材料技术领域，提供了一种高性能钢筋连接用套筒灌浆料及其制备方法，高性能钢筋连接用套筒灌浆料由硅酸盐水泥、硫铝酸盐水泥、石膏、提钛尾渣、保水剂、减水剂、消泡剂、PEA膨胀剂和级配石英砂组成，制备时将硅酸盐水泥、硫铝酸盐水泥、石膏、提钛尾渣、级配石英砂一起混合，再将其余原料一起加入混合。该灌浆料具有优良的物理力学性能，工作性能优异，易灌浆、不泌水，流动性好，且流动性经时损失小，可操作时间长，早期强度发展快，强度高，体积稳定性好，无收缩开裂问题。本发明制备方法简单，适用于装配式建筑用构件的钢筋连接用套筒灌浆工程，能在短期内即具有较高的力学性能，长期使用效能优异，确保工程质量和服役寿命。
