Effect of Carbon Dioxide Curing on the Carbonation Durability of Concrete

Concrete structures generate a large amount of carbon dioxide(CO2) during the production and construction of raw materials, exacerbating environmental problems such as greenhouse effect. In order to achieve low-carbon and environmentally friendly construction projects, a large number of new technologies and products have been developed to reduce carbon emissions when using Portland cement concrete. Among them, using carbon dioxide to cure newly poured concrete is an effective method of carbon sequestration. However, further research is needed on its carbon sequestration efficiency and whether it will have adverse effects on the durability of concrete structures. This article summarizes the research status of using carbon dioxide to cure concrete, analyzes its carbon fixation efficiency, and based on a concrete carbonation durability life prediction model, analyzes the impact of carbon dioxide curing concrete on carbonation durability life.
