Abstract
This document takes saline soil in Binzhou as the research object using smelter slag as the soil stabilizer to solid saline soil in Binzhou, which has been proved achieving good performance of saline soil solidification. The results show that the soil solidification developed indoors can be used in combination with low-dose lime to achieve good performance in solidification of saline soil. The 7d strength is relatively higher than that of both ordinary lime stabilized soil and lime-fly ash stabilized soil, which completely meet the unconfined compressive strength requirements of the base layer in the current technical specifications. The soil stabilizer can improve the unconfined compressive strength of the saline soil, especially the post-14-day strength, and improve the immersion compressive strength and water stability of the cured saline soil. As the dosage of curing agent gets higher than seven percent, the 28d strength change of cured soil is no longer significant. The test result demonstrates that the dosage of curing agent should be less than seven percent.
