In this paper,the steel slag sheet was prepared by slurry casting,pressing dewatering and carbon dioxide curing.The effects of raw material content,dewatering pressure and curing methods on the mechanical properties of steel slag sheet were investigated.The experimental results show that the maximum flexural strength can be obtained when the water-binder ratio is 0.35.With the increase of cement content,hydrated lime content and wood fiber,the flexural strength of the sheet increases.With the increase of dewatering pressure,the flexural strength of the sheet first increases then decreases.With the increase of curing time,the flexural strength of the sheet increases.The shorter the length of alkali-resistant glass fiber,the greater the flexural strength of the sheet,and the maximum flexural strength can be obtained by adding 1.5％alkali-resistant glass fiber.
