Grouting material using air-quenched blast furnace slag as aggregate and preparation method thereof
The invention provides a grouting material using air-quenched blast furnace slag as aggregate and a preparation method thereof. The preparation method comprises the following steps: S1, mixing the air-quenched blast furnace slag, the cementing material and the water reducing agent to prepare a dry grouting material; s2, mixing and stirring the dry grouting material and water to prepare a wet grouting material; and S3, after the wet grouting material is poured into the working face, maintenance is conducted. The problem that the digestibility of traditional blast furnace slag is gradually reduced is solved, the comprehensive utilization rate of the blast furnace slag is increased, and the grouting material prepared from the air-quenched blast furnace slag as the aggregate is superior to a quartz sand grouting material in the aspects of fluidity, compressive strength, vertical expansion rate and the like.
本发明提供了一种利用风淬高炉渣作为骨料的灌浆料及其制备方法。本发明的制备方法包括如下步骤：S1：将风淬高炉渣、胶凝材料和减水剂混合，制得灌浆料干料；S2：将灌浆料干料与水混合搅拌，制得灌浆料湿料；S3：将灌浆料湿料灌注于工作面后进行养护。本发明解决了传统高炉渣消化能力逐渐降低的问题，提升了高炉渣的综合利用率，利用风淬高炉渣作为骨料制备的灌浆料在流动度、抗压强度以及竖向膨胀率等方面均优于石英砂灌浆料。
