Sleeve grouting material for steel bar connection and preparation method thereof
The invention relates to the technical field of steel bar connection processes, in particular to a sleeve grouting material for steel bar connection and a preparation method thereof. The sleeve grouting material for steel bar connection is prepared from the following components in parts by weight: 300 to 450 parts of clay, 100 to 150 parts of bone meal, 50 to 100 parts of rubber powder, 1-2 partsof a defoaming agent, 3-5 parts of a water reducing agent, 5-10 parts of an expanding agent, and 1-2 parts of an antirust agent. The sleeve grouting material for steel bar connection has the followingbeneficial effects that the sleeve grouting material for steel bar connection is powdery, easy to transport, relatively good in crack resistance, relatively small in volume change during molding, relatively good in fluidity and relatively high in applicability.
本发明涉及钢筋连接工艺的技术领域，尤其是涉及一种钢筋连接用套筒灌浆料及其制备方法。该钢筋连接用套筒灌浆料由下述以重量份表示的组分组成：黏土300‑450份；骨粉100‑150份；胶粉50‑100份；消泡剂1‑2份；减水剂3‑5份；膨胀剂5‑10份；防锈剂1‑2份。本发明具有以下有益效果：钢筋连接用套筒灌浆料为粉状，易运输，且抗裂缝的能力较好，成型时体积变化较小，流动性较好，适用性较强。
