Cement-based grouting material for semi-flexible pavement and preparation method of cement-based grouting material
The invention discloses a cement-based grouting material for a semi-flexible pavement and a preparation method of the cement-based grouting material. The cement-based grouting material is prepared from the following components: 38 to 70 parts of quick-hardening sulphoaluminate cement, 10 to 35 parts of silica fume, 10 to 30 parts of fine aggregate, 0.01 to 0.6 part of nano ettringite early strength agent, 0.1 to 0.5 part of a water reducing agent, 0.01 to 0.1 part of a defoaming agent, 0.5 to 2.5 parts of an expanding agent and 20 to 35 parts of water. Compared with other grouting materials, the cement-based grouting material for the semi-flexible pavement has the characteristics of high early strength, uniform and stable slurry after being mixed with water, no bleeding and segregation, good combination with an asphalt mixture and the like, can realize road opening within 2-4 hours, and has wide popularization prospects and application values.
本发明公开了一种半柔性路面用水泥基灌浆材料及其制备方法，由以下组分组成：快硬硫铝酸盐水泥38~70份、硅灰10~35份、细骨料10~30份、纳米钙矾石早强剂0.01~0.6份、减水剂0.1~0.5份、消泡剂0.01~0.1份、膨胀剂0.5~2.5份、水20~35份。本发明半柔性路面用水泥基灌浆材料与其它灌浆材料相比，具有早期强度高、与水拌合后浆体均匀稳定、不泌水离析，且与沥青拌合料结合良好等特点，可在2~4h实现道路开放，具有广阔的推广前景和应用价值。
