Early-strength, high-strength and self-expanding sleeve grouting material and preparation method thereof
The invention relates to the field of grouting materials, and particularly discloses an early-strength, high-strength and self-expanding sleeve grouting material and a preparation method thereof.The grouting material is prepared from, by weight, 250-330 parts of magnesium oxide, 87-175 parts of magnesium sulfate, 25-33 parts of metakaolin, 1.25-1.65 parts of whisker inducer, 550-650 parts of filler and 120-150 parts of water; the whisker inducer is at least one of sodium laurate, lauric acid and potassium laurate. The grouting material disclosed by the invention has excellent early strength performance, the compressive strength reaches the standard of an ultrahigh-strength sleeve grouting material, and meanwhile, the grouting material has proper self-expansion performance and moderate setting time.
本申请涉及灌浆料领域，具体公开了一种早强、高强和自膨胀型套筒灌浆料及其制备方法，灌浆料按重量份包括以下组分：氧化镁250‑330份，硫酸镁87‑175份，偏高岭土25‑33份，晶须诱导剂1.25‑1.65份，填料550‑650份，水120‑150份；所述晶须诱导剂为月桂酸钠、月桂酸、月硅酸钾中的至少一种。本申请的灌浆料具有优异的早强性能，而且抗压强度达到于超高强套筒灌浆料的标准，同时具有合适的自膨胀性能，且凝结时间适中。
