There　is　large-area　saline　sludge　which　should　be　stabilized　in　China.　In　this　experiment,　cementitious　component　(cement),　alkaline　component　(Ca(OH)(2))　and　expansive　component　(sulfuraluminate　cement　or　gypsum)　were　used　as　compound　stabilizer　with　different　combinations　to　stabilize　artificial　saline　sludge,　then　the　unconfined　compressive　strength　of　stabilized　soil　samples　was　determined,　and　the　hydration　products　of　the　stabilized　soil　were　analyzed　by　XRD,　the　stabilizing　mechanism　and　the　required　hydrate　species　of　stabilized　soil　were　preliminary　explored.　The　results　show　that　the　unconfined　compressive　strength　of　stabilized　soil　increases　gradually　with　the　increase　of　the　cement　content;　when　partial　cement　replaced　by　right　amount　of　CH,　the　strength　reaches　the　maximum　and　higher　than　that　of　soil-cement;　the　use　of　sulfuraluminate　cement　plaster　as　expansive　component　for　stabilizing　saline　sludge　has　a　relatively　good　overall　affect　compared　to　the　gypsum;　possible　reasons　for　these　results　were　speculated　at　the　same　time.
