Early-strength grouting material for semi-flexible pavement as well as preparation method and application of early-strength grouting material
Aiming at the defects in the prior art, the invention provides a semi-flexible pavement cement-based grouting material as well as a preparation method and application thereof. The invention relates to a cement-based grouting material for a semi-flexible pavement. The cement-based grouting material is prepared from the following substances in parts by mass: 80-100 parts of water, 0.5-2.5 parts of a water reducing agent, 0.5-2.5 parts of an interface modifier, 0.5-2.5 parts of an early strength agent, 170-200 parts of cement, 55-70 parts of superfine sand, 8-18.5 parts of limestone mineral powder, 6-18 parts of fly ash and 10-20 parts of an expanding agent. The semi-flexible pavement cement-based grouting material provided by the invention has the characteristics of quick hardening, super early strength, excellent flowing property, uniformity after being mixed with water, no bleeding, no shrinkage after hardening and good combination with a matrix asphalt mixture.
针对现有技术不足，本发明提供一种半柔性路面水泥基灌浆材料及其制备方法和应用。本发明一种半柔性路面用水泥基灌浆材料，由以下质量份的各物质组成：水80～100，减水剂0.5～2.5，界面改性剂0.5～2.5，早强剂0.5～2.5，水泥170～200，特细砂55～70，石灰岩矿粉8～18.5，粉煤灰6～18，膨胀剂10～20。本发明所提供半柔性路面水泥基灌浆材料具有快硬、超早强、流动性能优越、与水拌合后均匀、不泌水、硬化后无收缩且与母体沥青混合料结合良好的特点。
