Ecological cement high-strength grouting material and preparation method thereof
The invention provides an ecological cement high-strength grouting material and a preparation method thereof. The ecological cement high-strength grouting material has the advantages of high flowability, favorable constructability, long operable time and smooth and flat surface after completion, and can perform self-remaining leveling. The ecological cement high-strength grouting material comprises a cementing material, aggregate and an additive, wherein the cementing material comprises slag powder, desulfurized gypsum and an alkaline activator; the aggregate is prepared from, by weight, 250-300 parts of 20-40-mesh quartz sand, 100-150 parts of 40-70-mesh dried sand and 100-150 parts of 70-120-mesh dried sand; and the additive comprises, by weight, 1-2 parts of a water reducing agent, 0.1-0.6 part of a retarder, 0.1-0.3 part of a plastic expanding agent and 0.1-0.3 part of a defoaming agent.
本发明提供了一种生态水泥高强灌浆料及制备方法，具有较大的流动性，施工性好，能够自留找平，可操作时间长，且完工后表面光滑平整。生态水泥高强灌浆料，包括胶凝材料、骨料和外加剂；胶凝材料包含以下原料矿渣粉，脱硫石膏，碱性激发剂；骨料包含以下重量份数原料：20‑40目石英砂：250‑300份40‑70目烘干砂：100‑150份70‑120目烘干砂：100‑150份外加剂包含以下重量份数原料：减水剂：1‑2份缓凝剂：0.1‑0.6份塑性膨胀剂：0.1‑0.3份消泡剂：0.1‑0.3份。
