This study investigated the potential of using water reducer (WR) to enhance the mechanical and durability properties of cement-treated soil. WRs have long been used in Portland cement concrete (PCC) to increase the properties of PCC. When added at a small dosage, WR helps improve the dispersion of cement particles and release the water otherwise entrapped in cement clusters, thus reducing the water demand for the same consistency or increase the consistency of PCC without adding more water. Cement-treated soil uses similar raw materials and has similar chemical compositions to PCC. However, little research has been conducted to explore the potential of using WR in cement-treated soil to improve its compaction and thus its mechanical and durability properties. In this study, a laboratory experiment was conducted to examine the effects of WR on the compaction characteristics and engineering properties of cement-treated soil. As expected, similar benefits of water reduction and improved properties could be achieved by adding WR in cement-treated soil. The improved mechanical and durability properties of cement-treated soil were due to the fact that WR could improve the compaction behavior of cement-treated soil through reduced optimum moisture content and increased maximum dry density. Further studies are recommended for the interaction among WR, soil particles, and cement particles to achieve an optimal effect for engineering applications.

这项研究调查了使用减水剂（WR）增强水泥处理过的土壤的机械和耐久性能的潜力。WR长期用于波特兰水泥混凝土（PCC）中，以提高PCC的性能。当以小剂量添加时​​，WR有助于改善水泥颗粒的分散性，并释放原本滞留在水泥团簇中的水，从而减少相同浓度的需水量或增加PCC的浓度而无需添加更多的水。水泥处理过的土壤使用的原料相似，化学成分与PCC相似。但是，很少有研究探索在水泥处理过的土壤中使用WR来改善其压实度，从而改善其机械性能和耐久性的潜力。在这项研究中，进行了一项室内实验，以检验WR对水泥处理过的土壤的压实特性和工程特性的影响。如预期的那样，通过在水泥处理过的土壤中添加WR，可以达到减少水分和改善性能的类似好处。水泥处理过的土壤的机械性能和耐久性得到了改善，这是由于WR可以通过降低最佳含水量和增加最大干密度来改善水泥处理过的土壤的压实性能。建议进一步研究WR，土壤颗粒和水泥颗粒之间的相互作用，以实现工程应用的最佳效果。通过在水泥处理过的土壤中添加WR，可以达到类似的减水效益和改善性能的效果。水泥处理过的土壤的机械性能和耐久性得到了改善，这是由于WR可以通过降低最佳含水量和增加最大干密度来改善水泥处理过的土壤的压实性能。建议进一步研究WR，土壤颗粒和水泥颗粒之间的相互作用，以实现工程应用的最佳效果。通过在水泥处理过的土壤中添加WR，可以达到类似的减水效益和改善性能的效果。水泥处理过的土壤的机械性能和耐久性得到了改善，这是由于WR可以通过降低最佳含水量和增加最大干密度来改善水泥处理过的土壤的压实性能。建议进一步研究WR，土壤颗粒和水泥颗粒之间的相互作用，以实现工程应用的最佳效果。
