Concrete is being widely used in various types of infrastructures. CO₂ emission happens during the life cycle stages of concrete, and the emission of CO₂ becomes an urgent problem to be solved in the concrete industry. Low CO₂ concrete is a new type of concrete with low CO₂ emission and comparable performance to ordinary concrete. Governments, industry, and the research community are very concerned about material design, structural design, and construction methods of low CO₂ concrete. This Special Issue will provide a broad communication platform for low CO₂ concrete and highlight realistic and feasible directions for government decision-making and industrial production of low CO₂ concrete. The Special Issue will introduce the latest progress in low CO₂ concrete and contribute to the development of  low CO₂ society. The topics of this Special Issue include but are not limited to the following: material design of low CO₂ concrete; hydration performance; mechanical properties and durability of low CO₂ concrete; workability and construction methods of low CO₂ concrete; structural design considering  CO₂ emissions; the application of multi-scale methods in low CO₂ concrete. In addition, this Special Issue also covers the CO₂ uptake of hardened concrete due to the carbonation and carbonation curing of fresh concrete.
Keywords: Material design of low CO₂ concrete; Hydration performance; Mechanical properties; Durability and sustainability; Working performance and construction methods; Structural design considering CO₂ emissions; Multi-scale study in low CO₂ concrete; CO₂ uptake of hardened concrete; Carbonation curing.
