High-flow-state early-strength semi-flexible pavement grouting material and preparation method thereof
The invention discloses a high-flow-state early-strength semi-flexible pavement grouting material and a preparation method thereof, and the grouting material comprises the following components in parts by weight: 25-55 parts of cement, 35-50 parts of slag, 15-30 parts of modified fly ash microbeads, 10-30 parts of fine aggregate, 1-2 parts of desulfurized gypsum, 30-70 parts of an alkali activator, 10-20 parts of sodium hydroxide, 0.1-0.5 part of an early strength agent, 1-5 parts of an expanding agent, 1-3 parts of a water reducing agent, 0.5-1 part of a defoaming agent and 50-110 parts of water. The semi-flexible pavement grouting material provided by the invention is a composite grouting material with early strength, rapid hardening, high fluidity, micro-expansion and strong binding power with an asphalt mixture, on one hand, the early strength of the grouting material is improved through the alkali activator, and on the other hand, the fluidity of the grouting material is optimized through the ball effect of the fly ash microbeads. According to the semi-flexible pavement grouting material rotary oscillation stirring device, the uniformity of the prepared grouting material can be improved, and the performance of the grouting material is more excellent. The semi-flexible pavement grouting material prepared by the invention is convenient to construct and high in cost performance, and has wide popularization prospects and application values.
本发明公开了一种高流态早强型半柔性路面灌浆料及其制备方法，包括以下组分，按重量份计：水泥25～55份、矿渣35～50份、改性粉煤灰微珠15～30份、细骨料10～30份、脱硫石膏1～2份、碱激发剂30～70份、氢氧化钠10～20份、早强剂0.1～0.5份、膨胀剂1～5份、减水剂1～3份、消泡剂0.5～1份、水50～110份。本发明提供的半柔性路面灌浆料是一种具有早强快硬、高流动度、微膨胀且与沥青混合料粘结力强的复合灌浆料，一方面通过碱激发剂提升灌浆料的早期强度，另一方面通过粉煤灰微珠的滚珠效应优化其流动性。本发明的半柔性路面灌浆料回旋振荡搅拌装置，能够提升制得灌浆料的均匀性，使其性能更加优越。本发明制得的半柔性路面灌浆料施工便捷、性价比高，具有广阔的推广前景和应用价值。
