Cement-based grouting material for semi-flexible pavement
The invention discloses a cement-based grouting material for a semi-flexible pavement. The cement-based grouting material comprises, by mass, 25-40 parts of silica fume, 15-20 parts of fly ash, 20-30parts of limestone powder, 3-6 parts of limestone mineral powder, 0.2-0.3 part of triisopropanolamine, 6-8 parts of phenylpropionic acid, 8-10 parts of phthalic anhydride, 6-8 parts of trimethylolpropane, 2-5 parts of a thickening agent, 14-18 parts of rubber powder, 5 parts of a water reducing agent, 3-5 parts of bauxite, 10-12 parts of kaolin, 2-4 parts of iron oxide yellow and 40-50 parts of water. Compared with other grouting materials, the cement-based grouting material for the semi-flexible pavement is rapid in hardening, early in strength, uniform, stable and free of separation after being mixed with water, good in combination with an asphalt mixture and free of shrinkage after being hardened.
本发明公开了一种半柔性路面用水泥基灌浆材料，由如下质量份数的组分组成：25～40份硅灰、15～20份粉煤灰、20～30份石灰石粉、石灰岩矿粉3～6份，三异丙醇胺0.2～0.3份、6～8份苯丙酸、8～10份邻苯二甲酸酐、6～8份三羟甲基丙烷、2～5份增稠剂、14～18份胶粉、5份减水剂、3～5份铝矾土、10～12份高岭土、2～4份氧化铁黄以及40～50份水。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，快硬、早强、与水拌合后均匀、稳定、不离析、与沥青混合料结合良好、硬化后无收缩。
