In this paper, to investigate the microstructural characteristics of MgO concrete according to cement manufactures, it was carried out XRD, SEM, DSC and Autoclave test. For two types of cement, the micro structural characteristics were observed by test variation of curing temperature and MgO mixing ratio until age 1 year. DSC was conducted with curing temperature of 20, 30, 40℃ and MgO mixing ratio of 0% and 5%. XRD and SEM were conducted with curing temperature of 20, 40℃ and MgO mixing ratio of 0% and 10%. Autoclave test was conducted with MgO mixing ratio of 0%, 3% and 5%.
