Experimental Study on the Influence of Snow-Melting Agents on Fiber-Reinforced Cemented Soil under Freezing-Thawing Cycles

To explore the effect of snow-melting agents on glass fiber-reinforced cemented soil under freezing-thawing cycles, three widely used agents, including potassium acetate, magnesium chloride, and sodium sulfate, were in this article. The effects agent types apparent damage, mass loss, mechanical properties cycles analyzed through salt freezing unconfined compressive strength tests. results show that acetate is best, chloride second, sulfate worst. Notably, as number increases, test block decreases to varying degrees. After fifth cycle, without fiber decreased by 61.30%, 70.22%, 81.58% clear water, solution, respectively, while solution lost its bearing capacity. A series studies proved with main component has most erosion soil, followed weakest. incorporation can effectively improve resistance action various coupling a significant slowing development surface cracks, improving peak strength, reducing loss rate. This research will provide theoretical support for design subgrade selection cold areas.
