Reinforcing steel bar sleeve grout and preparation method thereof

The invention provides reinforcing steel bar sleeve grout and a preparation method thereof, and relates to the field of building. The reinforcing steel bar sleeve grout is prepared from 90-110 parts of cement, 0-90 parts of quartz sand, 20-110 parts of river sand, 10-20 parts of an expansion agent, 0-2 parts of a retarder, 1-4 parts of a water reducing agent, 1-2 parts of a defoaming agent and 20-85 parts steel slag. The reinforcing steel bar sleeve grout and the preparation method thereof can reduce cost under the premise of guaranteeing the strength of the grouting material. 本发明提供种钢筋套筒灌浆及制备方法，具体涉及建筑领域，水泥90至110份，石英砂0至90份，河砂20至110份，膨胀剂10至20份，缓凝剂0至2份，减水剂1至4份，消泡剂1至2份，钢渣20至85份。本发明可在保证灌浆料强度下，降低成本。
