This study generally compared and investigated cement type and quality of China and Korea. Cement in Korea is divided into five such as ordinary, high early strength, moderate heat, low heat and sulfate resistance portland cement. However cement in China is divided into portland cement($P{\cdot}I,\;P{\cdot}II$) and ordinary portland cement($P{\cdot}O$) with admixture displacement ratio and it is again divided into 6 level and 7 level with 28 days compressive strength. In addition China classified cement into several standards, such as Mgo, SO3,, igloss, blame, setting time, stability, strength, alkali and sampling test. Therefore it should be careful to conclude so quickly without right understanding whether quality of China cement is bad or good. The better way to evaluate China cement is synthetically understanding a value engineering and consumer awareness.
