Grouting material for expansive soil dam cracks and preparation method thereof
The invention provides a grouting material for expansive soil dam cracks and a preparation method of the grouting material, and belongs to the technical field of grouting materials. The grouting material comprises the cement, the fly ash, the expansive soil and the water, the expansive soil is used for replacing common clay, so that the grouting material has a better water retention effect, a lower bleeding rate and a higher stone rate, a small amount of superfine fly ash is added to improve the flowability of slurry, and different proportions are adjusted to adapt to cracks with different characteristics, so that the grouting material is suitable for cracks with different characteristics. The grouting effect is improved, and the construction cost is reduced.
本发明提供了一种用于膨胀土土坝裂缝的注浆材料及其制备方法，属于注浆材料技术领域。本发明的注浆材料包含水泥、粉煤灰、膨胀土和水，本发明用膨胀土代替普通粘土，使之具有更好的保水效果，析水率更低而结石率更高，加入少量超细粉煤灰以改善浆液的流动性，调整不同的配比来适用于具有不同特性的裂缝，以提高注浆效果和减少工程造价。
