可用于工程的土壤需要达到一定的强度特性，以满足其预期用途。一些可用的土壤，如黑棉土，往往强度较弱，需要对其进行改性，以达到所需的强度，这可以使用能够改善土壤性质的材料，如石膏、石灰、甘蔗渣灰、水泥等来实现。本文综述了石膏与其他稳定材料比例使用以改善土壤强度特性的可行性。研究表明，石膏与其他稳定材料（如甘蔗渣灰、稻壳、石灰、氯化钠、锡、粉煤灰、黄麻纤维等）相比，可产生更好的稳定土壤。使用石膏和其他添加剂确定稳定土壤的最大干密度和最佳含水量、无侧限抗压强度、加州承载比CBR和阿太堡极限值的一系列试验后的实验室结果，揭示了使用石膏和任何其他添加剂进行有效的土壤稳定取决于被稳定的土壤类型、添加剂的性质、所用添加剂的百分比、固化时间以及待稳定土壤的分类。研究发现，这些添加剂的使用比例、它们的百分比比例、养护时间和土壤的性质会导致稳定土壤的不同终点。
