Oceans　and　saline　soil　environments　strongly　demand　for　concrete　with　high　compressive　strength　and　high　chlorine　salt　corrosion　resistance.　Herein,　a　new　preparation　process　of　geopolymer　concrete　with　high　compressive　strength　and　chlorine　salt　corrosion　resistance　was　established,　and　the　process　was　optimized　by　adjusting　the　water/cement　ratio,　the　proportion　of　Na2O　and　the　amount　of　fly　ash.　Mechanical　properties　tests　show　that　the　compressive　strength　of　geopolymer　concrete　increases　with　increase　in　Na2O　proportion　but　decreases　with　increase　in　water/cement　ratio　and　fly　ash.　The　compressive　strength　of　geopolymer　concrete　is　as　high　as　96.20　MPa,　when　the　water/cement　ratio　is　0.6,　the　proportion　of　Na2O　is　0.12,　and　the　amount　of　fly　ash　is　10%.　This　may　be　because　the　C-(A)-S-H　gel　makes　the　geopolymer　concrete　denser.　At　the　same　time,　electrochemical　impedance　spectroscopy　and　Tafel　results　imply　that　the　geopolymer　concrete　also　has　great　chlorine　salt　corrosion　resistance,　the　lowest　weight　loss　rate　of　steel　bar　is　only　0.06%　after　240　h　accelerated　corrosion.　The　leaching　tests　indicate　that　at　the　same　depth,　the　total　and　free　chloride　ions　in　geopolymer　concrete　are　minimum　and　some　chloride　ions　are　combined.　The　high　chlorine　salt　corrosion　resistance　could　be　attributed　to　the　increase　in　C-(A)-S-H　gel　which　refines　the　pore　structure　of　concrete,　improves　concrete　compactness　and　binds　the　chloride　ions.　This　paper　provides　a　new　method　for　the　high-quality　utilization　of　solid　waste　and　a　potential　clue　for　the　preparation　of　high-performance　concrete.
