There　is　a　large　area　of　high　saline　dredger　fill　in　China＇s　coastal　areas　that　are　needed　to　be　stabilized.　Self-made　stabilizer　A　and　portland　cement　are　adopted　to　stabilize　the　dredger　fill　collected　from　the　Tianjin　Binhai　New　Area.　The　salinity　of　the　dredger　fill　is　8%.　Under　the　mixing　ratio　of　10%　and　15%,　the　strengths　of　the　stabilized　soil　by　means　of　the　stabilizer　A　are　increased　by　2.4　times　and　1.7　times　than　those　by　use　of　the　portland　cement,　respectively.　The　results　from　the　scanning　electron　microscopy　(SEM),　X-ray　Diffraction　(XRD)　and　energy-dispersive　X-ray　(EDXA)　tests　show　that　when　using　the　stabilizer　A　to　stabilize　the　soil　sample　TT,　besides　generating　similar　hydration　products　with　portland　cement,　the　stabilizer　A　can　react　with　NaCl　in　the　soil　sample　TT　to　generate　Ca4Al2Cl2O6　·　10H2O,　which　greatly　increases　the　strength　of　the　stabilized　dredger　fill　by　its　solid　volume　expansion.
