Early-strength and high-strength sleeve grouting material and preparation method thereof
The invention discloses an early-strength and high-strength sleeve grouting material. Comprising the following components in parts by weight: 430-500 parts of Portland cement clinker, 15-50 parts of double-fast sulphoaluminate cement, 20-40 parts of silicon powder, 50-200 parts of silica powder, 220-350 parts of medium-fine quartz sand, 2-5 parts of a polycarboxylic acid powder water reducing agent, 20-80 parts of a plastic expanding agent, 0.3-0.5 part of a powder defoaming agent, 1-2 parts of lithium carbonate, 5-10 parts of a rheological agent, 50-100 parts of a composite additive and 20-40 parts of high-strength synthetic fiber. The invention further discloses a preparation method of the early-strength and high-strength sleeve grouting material. According to the early-strength and high-strength sleeve grouting material, the final setting time of the sleeve grouting material is shortened without influencing the normal grouting opening time, the assembly efficiency is improved, and the integrated installation time of a prefabricated and assembled bridge column and a cover beam is shortened. The grouting sleeve anchoring corrugated pipe has high compressive strength stability and breaking strength, can be pressed and injected into grouting sleeve anchoring corrugated pipes of various specifications, and is not easy to block the pipe and not compact in sleeve joint slurry.
本发明公开了一种早强高强套筒灌浆材料，包括以下组分及其重量份数：硅酸盐水泥熟料430‑500份、双快硫铝酸盐水泥15‑50份、硅粉20‑40份、硅微粉50‑200份、中细石英砂220‑350份、聚羧酸粉体减水剂2‑5份、塑性膨胀剂20‑80份、粉体消泡剂0.3‑0.5份、碳酸锂1‑2份、流变剂5‑10份、复合添加剂50‑100份和高强合成纤维20‑40份。本发明还公开了一种早强高强套筒灌浆材料的制备方法。本发明早强高强套筒灌浆材料在不影响正常灌浆开放时间内将套筒灌浆材料的终凝时间缩短，提高装配效率，缩短了预制拼装桥梁柱、盖梁一体化安装时间。本发明具有较高的抗压强度稳定性与抗折强度，能压注至各种规格的灌浆套筒锚固波纹管内，不易发生堵管和套筒接头浆料不密实现象。
