Sleeve grouting material for steel bar connection and preparation method and application thereof
The invention provides a sleeve grouting material for steel bar connection and a preparation method and application thereof.The sleeve grouting material is composed of a component A and a component B.The component A is dry powder and comprises, by mass, 400-600 parts of cement, 10-40 parts of mineral admixture, 400-600 parts of sand, 0.2-3.0 parts of plastic expanding agent, 15-25 parts of expanding agent, 1-3 parts of water reducing agent, 0.2-1.0 part of defoaming agent, 0.1-1.0 part of stabilizer, 0-10 parts of antifreezing agent, 0-5 parts of an early strength agent, and 0-5 parts of a retarder; and the component B is water and comprises, in parts by mass, 120-170 parts of water. The sleeve grouting material has the characteristics of high fluidity, micro-expansion, high strength andthe like, and can be suitable for construction at different temperatures (-5 to 10 DEG C) and normal temperature (higher than 10 DEG C).
本发明提供一种钢筋连接用套筒灌浆料及其制备方法和应用，该灌浆料由A、B两组分组成，A组分为干粉料，按照质量份数计，包含水泥400～600份、矿物掺和料10～40份、砂400～600份、塑性膨胀剂0.2～3.0份、膨胀剂15～25份、减水剂1～3份、消泡剂0.2～1.0份、稳定剂0.1～1.0份、防冻剂0～10份、早强剂0～5份、缓凝剂0～5份；B组分为水，按照质量份数计，为120～170份。该灌浆料具有大流动性、微膨胀、高强度等特点，可以适用于低温(‑5～10℃)、常温(>10℃)不同温度施工。
