Sleeve grouting material for fabricated residences and preparation method of sleeve grouting material
The invention relates to a sleeve grouting material for fabricated residences and a preparation method of the sleeve grouting material. The grouting material comprises 35-40 parts by mass of cement, 10-15 parts by mass of mineral powder, 5-10 parts by mass of fly ash, 15-20 parts by mass of 1-2 mm steel slag particles, 20-25 parts by mass of 2-3 mm steel slag particles, a water reducing agent accounting for 0.05%-0.20% of the material dosage, a defoaming agent accounting for 0.03% of the material dosage, an expanding agent accounting for 0.03% of the material dosage and water accounting for 0.2-0.3 time of the material dosage. The sleeve grouting material is achieved by designing a concrete mixing ratio, doping steel slag particles for reinforcement, improving the cement grade, reducing the hydration heat of cement, reducing pores in concrete, improving the flowability of concrete and the like.
本发明涉及一种装配式住宅用套筒灌浆料及其制备方法，灌浆料包括35‑40质量份的水泥、10‑15质量份的矿粉、5‑10质量份的粉煤灰、15‑20质量份的1‑2mm钢渣颗粒、20‑25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。
