Abstract: Tailings are an industrial waste residue. If effectively improved, not only is it beneficial to improve the stability of the tailings dams, but also it can also convert tailings into valuable resources and achieve the resource utilization of waste. This article obtains the strength characteristics of the Tin Tailing Silty Sand (TTSS) improved by the inorganic composite curing agent, epoxy resin curing agent and Supplementary Coat Additive (SCA) curing agent through unconfined compressive strength test. It is studied that the compressive strength of the TTSS improved by three curing agents has been improved with the increase of curing time, but there are differences in the magnitude of the increase in sample strength and the required curing time. As the ratio of three curing agents increases, the compressive strength of the samples is also improved to varying degrees. Among them, the influence of slag and cement in inorganic composite curing agents on the strength characteristics of the TTSS is more significant.
