摘要
通过使用再生石膏和粉煤灰作为稳定剂来提高软土的强度及耐久性能,试验结果表明,添加不同比例的石膏和粉煤灰可以显著提高软土的强度及耐久性,单独添加粉煤灰则对土体强度有轻微的负效应,早期固化时间对软土强度提高具有显著的影响。
This study investigates the use of recycled bassanite,in conjunction with coal ash as a stabiliser material to improve the strength of soft clay soil as well as to improve its durability.The results showed that the use of recycled bassanite and coal ash significantly increase strength and improve durability.The use of coal ash alone is not recommended because it has a slightly negative effect on soil strength.Curing time has a significant effect on the improvement of strength in the early days.
