As a high-efficiency and environment-friendly stabilizer material, ionic soil stabilizer (ISS) has been widely used in construction industries. However, the microstructure characteristics and mechanical behavior of the treated soil still need a case study based on vary characteristics of soils and different treatments. In this paper, microscopic and macroscopic testing methods were adopted to explore the microstructure characteristics and mechanical behavior of the acidic ISS-treated clay versus the traditional alkaline lime and cement-treated clay. The results indicate that the soil particles become much more flocculated because of the ion exchange reaction between the soil and the ISS relying on the unique molecular structure of the ISS. The unconfined compressive strength (UCS) significantly increases, but still could not satisfy the requirement of road bearing capacity. However, the UCS improves rapidly with the increase of alkaline lime and cement. In addition, there is a benefit-period when the UCS of acidic and alkaline stabilizer-treated soil is greater than that of lime and cement-treated soil, whereas the strength of lime and cement-treated soil is lower than that of the combined treated one after this period. This study investigates the microstructure characteristics and mechanical behavior of the ISS-treated clay, which provides a theoretical and scientific support for appropriate road construction.

探索离子土壤稳定剂处理过的粘土的微观结构特征和力学性能

作为一种高效，环保的稳定剂材料，离子土壤稳定剂（ISS）已被广泛应用于建筑行业。然而，处理过的土壤的微观结构特征和力学行为仍然需要基于不同的土壤特征和不同处理方法进行案例研究。本文采用微观和宏观的测试方法来探讨酸性ISS处理粘土与传统碱性石灰和水泥处理粘土的微观结构特征和力学性能。结果表明，由于土壤与国际空间站之间的离子交换反应依赖于国际空间站的独特分子结构，土壤颗粒变得更加絮凝。无边抗压强度（UCS）显着增加，但仍不能满足道路承载力的要求。但是，随着碱性石灰和水泥的增加，UCS迅速提高。另外，当酸性和碱性稳定剂处理过的土壤的UCS大于石灰和水泥处理过的土壤的UCS，而石灰和水泥处理过的土壤的强度低于混合处理后的土壤的UCS时，会有一个收益期在此之后的一个。这项研究调查了ISS处理过的粘土的微观结构特征和力学行为，这为适当的道路建设提供了理论和科学支持。当酸性和碱性稳定剂处理过的土壤的UCS值大于石灰和水泥处理过的土壤的UCS时，而石灰和水泥处理过的土壤的强度低于经过联合处理的土壤的强度时，则有一个有益期期。这项研究调查了ISS处理过的粘土的微观结构特征和力学行为，这为适当的道路建设提供了理论和科学支持。当酸性和碱性稳定剂处理过的土壤的UCS值大于石灰和水泥处理过的土壤的UCS时，而石灰和水泥处理过的土壤的强度低于经过联合处理的土壤的强度时，则有一个有益期期。这项研究调查了ISS处理过的粘土的微观结构特征和力学行为，这为适当的道路建设提供了理论和科学支持。
