Using Xixiayuan Reservoir sediment as the main raw material and S105 slag powder as the admixture, the influence of different Na2SiO3 content and different alkali excitators co-excitation on the compressive strength of Xixiayuan Reservoir sediment cemented blocks was investigated. The results show that the optimal doping amount of Na2SiO3 for single excitation is 8%. Double excitation can effectively improve the compressive strength of Xixiayuan sediment cemented blocks. With the increase of alkali activator content, excessive alkali appears in the cemented block, which affects the compressive strength.
