Abstract

Searching for the best soil stabilizer to overcome problems occur by the soft soils are still being the main concern, not only to achieve the required soil engineering properties but also by considering the cost and the effect to the environment. This review paper presents the results of experimental researches on soil stabilization by using the most chemical admixtures, which involved cement, lime and fly ash, and their effectiveness in the engineering properties of soil. Based on the literature review, the results show that addition of these chemical additives lead to significant improvement in workability, strength, durability and mechanical behaviour. On the other hand, it lead to a reduction in shrinkage, plasticity, compressibility and swell characteristics of soil. Also, the curing duration had significantly improved the strength properties of the stabilized soil with chemical additives. Using of each chemical additive and its suitability for a specific soil is highlighted in the research.
化学外加剂稳定土壤的研究进展
寻找最佳的土壤稳定剂来克服软土出现的问题仍然是人们关注的主要问题,不仅要达到所需的土壤工程性能,而且要考虑成本和对环境的影响。本文综述了水泥、石灰、粉煤灰等常用化学外加剂稳定土壤的试验研究结果及其对土壤工程特性的影响。根据文献综述,结果表明,添加这些化学添加剂可以显著改善加工性能、强度、耐久性和机械性能。另一方面,导致土的收缩、塑性、压缩性和膨胀特性降低。同时,养护时间的延长也显著提高了添加化学添加剂的稳定土的强度特性。每种化学添加剂的使用及其对特定土壤的适用性是研究的重点。
