Special grouting material for semi-flexible pavement and preparation method thereof
The invention discloses a special grouting material for semi-flexible pavement, which comprises the following components in parts by weight: 80-90 parts of river sand, 65-75 parts of cement, 19-24 parts of coal ash, 8-11 parts of an expanding agent, 2-3 parts of a water reducing agent and 0.5-1.5 parts of a defoaming agent. A preparation method of the special grouting material comprises the following specific steps: S1, washing and drying the river sand for later use, respectively and sequentially putting the dried river sand, cement and coal ash into a mixing container, and performing crushing treatment; S2, uniformly mixing the river sand, the cement and the coal ash together; and S3, adding the expanding agent, the water reducing agent and the defoaming agent, and stirring to obtain the grouting material. The prepared grouting material has better stability, fluidity and compressive strength.
本发明公开了一种半柔性路面专用灌浆材料，包括以下按重量份计的各组分：河砂80~90份、水泥65~75份、煤灰19~24份、膨胀剂8~11份、减水剂2~3份和消泡剂0.5~1.5份，其制备方法，包括以下具体步骤：S1、将河砂洗净烘干后备用，分别取干燥的河砂、水泥和煤灰依次投入混合容器中，进行粉碎处理；S2、将河砂、水泥和煤灰均匀混合在一起；S3、加入膨胀剂、减水剂和消泡剂，再搅拌得到灌浆材料。本发明制备的灌浆材料具备更好的稳定性、流动性和抗压强度。
