Abstract A series of studies was conducted to assess the carbonation-based service life of concrete mixtures produced in various regions of South Korea. In this article, as the first report on these research findings, the basic properties and carbonation rate values of representative concrete mixtures produced in different regions were investigated to confirm their distribution. Raw materials for producing concrete were selected for six representative regional groups across the country, and mix designs were carried out for various levels of compressive strength and slump. The results revealed that while practical concrete in South Korea varies in the mixture of mineral admixtures and aggregates depending on the region, it demonstrates more conservative resistance to carbonation than the values used in durability design, as long as the quality of the concrete is managed to achieve appropriate performance.
