High-performance sleeve grouting material for prefabricated buildings and preparation method thereof
The invention discloses a high-performance sleeve grouting material for prefabricated buildings and a preparation method thereof. The sleeve grouting material comprises the following raw materials inparts by weight: 35-50 parts of cement, 30-45 parts of quartz sand, 5-10 parts of fly ash, 5-10 parts of mineral powder, 1-2 parts of an ultramicro admixture, 0.2-0.4 part of a water reducing agent, 0.05-0.12 part of a defoaming agent, 0-8 parts of an expanding agent, 0-1 part of an early strength agent, 0-0.1 part of a retarder, 0-0.05 part of a thickening agent and 0-10 parts of thermoplastic elastomer particles modified by a titanate coupling agent. The preparation method comprises the following steps: firstly, mixing and stirring the cement, the fly ash, the mineral powder, the ultramicroadmixture, the water reducing agent, the defoaming agent, the expanding agent, the early strength agent, the retarder, the thickening agent and the modified thermoplastic elastomer particles; then adding the quartz sand in batches with stirring after each time of adding, thus producing the high-performance sleeve grouting material for the prefabricated building. According to the invention, the high-performance sleeve grouting material for the prefabricated building has the characteristics of good fluidity, no bubbles, no shrinkage in the later period, good vibration reduction performance, stable and reliable performance and high strength.
本发明公开一种装配式建筑用高性能套筒灌浆料及其制备方法。该套筒灌浆料包括如下重量份的原料：水泥35‑50份、石英砂30‑45份、粉煤灰5‑10份、矿粉5‑10份、超微掺合料1‑2份、减水剂0.2‑0.4份、消泡剂0.05‑0.12份、膨胀剂0‑8份、早强剂0‑1份、缓凝剂0‑0.1份、增稠剂0‑0.05份以及经钛酸酯偶联剂改性的0‑10份热塑性弹性体颗粒。其制备方法为：先将水泥、粉煤灰、矿粉、超微掺合料、减水剂、消泡剂、膨胀剂、早强剂、缓凝剂、增稠剂、改性热塑性弹性体颗粒混合搅拌；然后分批加入石英砂，每次加入后搅拌，得到装配式建筑用高性能套筒灌浆料。本发明的装配式建筑用高性能套筒灌浆料具有流动性好、无气泡、后期无收缩、减振性能佳、性能稳定可靠、强度高的特点。
