Steel slag is generated from steel making process，and it is similar to cement clinker in phase composition． However，steel slag has not been effective utilized in building materials because of its high free CaO content． This paper discussed the thermodynamics analysis and modification experimental of hot steel slag． Modification experimental result coincided very well with thermodynamics analysis． Utilizing CO2 gas as the modifier，phase composition of steel slag was improved greatly，and the amount of f-CaO reduced to less than 1%．
