摘要
甘蔗压榨泥(SPM)是制糖业产生的废物。印度每年生产约1200万吨SPM,因此需要有效的管理。本研究深入研究了SPM作为三元混合料在膨胀土水泥-石灰稳定中的应用。膨胀土稳定使用4.5%石灰(由Eades和Grim pH试验确定)和固定水泥含量1%的组合。通过铸造尺寸为38 mm x 76 mm的圆柱形试样,并将其固化7,14和28天,研究了稳定化的效果。通过将其与SPM作为三元添加剂混合,以1%的增量增加5%,对该工艺进行了改进。评估了SPM的最佳剂量,以提高强度增益,然后进行干湿循环,以了解含水量变化的影响。研究结果表明,水泥-石灰的稳定效果明显优于石灰单独稳定。1%的SPM是获得最大强度增益所需的最佳剂量。基于上述结果,认为三元复合材料具有潜在的土壤稳定作用。
Sustainable Management of Sugarcane Press Mud Waste as a Ternary Additive in Cement-Lime Stabilization of an Expansive Soil
: Sugarcane Press Mud (SPM) is a waste generated from the sugar industry. India generates about 12 million tonnes of SPM annually and hence, needs effective management. The present study delves into the use of SPM as a ternary blend in cement-lime stabilization of an expansive soil. An expansive soil was stabilized using a combination of 4.5% lime (determined from the Eades and Grim pH test) and a fixed cement content of 1%. The effect of the stabilization was studied by casting cylindrical specimens of dimensions 38 mm x 76 mm and curing them for periods of 7, 14 and 28 days. This process was modified by blending it with SPM as a ternary additive up to 5% in increments of 1%. The optimal dosage of SPM was evaluated for enhanced strength gain which was then subjected to a wet-dry cycle to understand the effect of variation in moisture content. The results of the investigation revealed that cement-lime stabilization of the soil was significantly better than lime stabilization alone. 1% SPM was found to be the optimal dosage required for maximum strength gain. Based on the results, it was concluded that ternary blending of SPM can potentially be beneficial in soil stabilization.
