摘要：
Concrete structures are the most common structures. However, the carbon emissions during the entire life of concrete structures have reached a non-negligible level. Developing the carbon emission reduction technologies (CERT) for concrete structures is essential to promote green development of construction industries. In terms of structural life-cycle, the service is divided into three stages, namely before the service (material preparation and construction), during the service (operation and maintenance), and after the service (destruction and recycling) . The total carbon emissions and the annual carbon emissions are proposed to describe the concept of carbon emission reduction. The research progress of CERT in each stage is presented, including applying novel low carbon cementitious materials,increasing the durability of concrete structures, and recycling the demolish waste. The design theory of life-cycle carbon emission reduction for concrete structures is also introduced, and a balanced design considering reliability, economy and carbon emission by multi-objective analysis is recommended. The future research and implementation of life-cycle carbon emission reduction for concrete structure is proposed. © 2024 Science Press. All rights reserved.
