Abstract: The CO2-curing concrete technology is a promising sustainable curing method, which based on the chemical reactions between CO2 and fresh concrete. By CO2-curing concrete technology, the fresh concrete could obtain higher early strength and denser microstructure. In another, the CO2-curing concrete technology is an environmentally friendly and energy-efficient method to consume CO2. This paper reviews and summarizes the development and latest research results of CO2 curing of concrete. The kinetics and mechanism of CO2-curing concrete technology, the effect of CO2-curing concrete on microstructure and the subsequent hydration of CO2-curing concrete are introduced. Finally, according to the review of previous studies, some recommendations will be given about the further research in this field.
