Abstract
The purpose of this study was to evaluate the North Korea cement industry and technology status by comparing and analyzing the cement standards and properties of South and North Korea. In the literature study, data on North Korea's cement industry and standards were collected and analyzed through the Ministry of Unification's North Korea Data Center and other agency. The facilities, classification, and quality standards of South and North Korea cements were compared. In an experimental study, a survey on the quality of cement in North Korea was carried out through physical and chemical analysis experiments by obtaining a small amount of cement from North Korea, and compared with domestic cement. As a result, North Korea cement was of lower quality than South Korean cements. North Korea cement had lower C3S and higher C2S than South Korea cement, especially the residue content was much higher. In addition, North Korea cement had about 50% of the compressive strength of cement in South Korea because the clinker was not fired at a sufficient temperature due to the poor performance of the cement facilities in North Korea.
