Abstract: The mechanism of chloride ion and sulfate ion for cement hydration products is analyzed,and the advantages and disadvantages of all kinds of cement used in ocean project are summarized,the existing varieties of cement performance cannot meet the requirements of ocean project are pointed out. Finally,it is suggested that the Portland cement for ocean project can be developed on the basis of low heat Portland cement by means of mineral composition optimization and ion doping method.
