Assembled pier sleeve grouting material and preparation method thereof
The invention relates to an assembled pier sleeve grouting material and a preparation method thereof. The grouting material comprises, by mass, 40-45 parts of cement, 5-10 parts of mineral powder, 5-10 parts of fly ash, 5-10 parts of 0.5-1mm steel slag particles, 15-20 parts of 1-2mm steel slag particles, 15-20 parts of 2-3mm steel slag particles, 0.05%-0.20% of a water reducing agent, 0.03% of anantifoaming agent, 0.03% of an expanding agent and 0.2-0.3 time of water. The grouting material is realized by designing a concrete mixing ratio, doping reasonably graded steel slag particles for reinforcement, improving the cement mark, reducing the hydration heat of cement, reducing pores in concrete, improving the flowability of concrete and the like.
本发明涉及一种拼装式桥墩套筒灌浆料及其制备方法，灌浆料包括40‑45质量份的水泥、5‑10质量份的矿粉、5‑10质量份的粉煤灰、5‑10质量份的0.5‑1mm钢渣颗粒、15‑20质量份的1‑2mm钢渣颗粒、15‑20质量份的2‑3mm钢渣颗粒、物料用量0.05%‑0.20%的减水剂、物料用量0.03%的消泡剂、物料用量0.03%的膨胀剂以及物料用量0.2‑0.3倍的水。本发明通过混凝土配合比设计、掺入合理级配的钢渣颗粒增强、提高水泥标号、降低水泥水化热和减少混凝土中气孔、提高混凝土流动性等方法实现。
