Energy·CO2 Minimum (ECM) concrete, one of Japan’s leading environmentally friendly concrete products, achieves a reduction of 60-70 % in CO2 emissions compared to conventional concrete by utilizing a significant amount of ground granulated blast furnace slag and using a binder that optimizes the type and dosage of gypsum, all while maintaining high quality. In this paper, slump retention, exothermic characteristics, strength development, shrinkage cracking resistance, durability and fire resistance are discussed as the properties of ECM concrete. In addition, examples of application to structures using these characteristics are described.
