报告内容简介：
In response to the accelerated pace of urbanization and the steady rise in global population, a palpable and inescapable consequence has manifested - a striking surge in CO2emissions, emerging as the foremost catalyst behind climate change. The concrete industry is a major CO2contributor, posing a considerable challenge in achieving carbon neutrality by 2050.
Efforts to mitigate CO2emissions in the construction industry have been extensive. Still, the current strategies mainly rely on passive reduction methods, such as decreasing clinker content in cement, using local resources, and implementing efficient design. To ensure satisfactory performance, the level of CO2reduction in passive strategy is inevitably limited. Despite the endeavors, global CO2emissions from the construction sector have reached an all-time high after the pandemic. To address this challenge, a shift towards an active carbon reduction strategy is necessary. This involves utilizing concrete used for buildings as CO2sinks, actively capturing and mineralizing CO2. By adopting this proactive approach, there is a potential to significantly expand the scope of carbon reduction and work towards achieving carbon neutrality. The CO2mineralization capability of early and later-age concrete provides a strong rationale for pursuing this direction. This study proposed to develop low-carbon concrete and technologies, including low-carbon raw materials for concreting, CO2-activated construction processes, sustainable concrete structures, and sustainability assessment framework, that circulate both greenhouse gas and solid wastes from the construction industry. This fully circular approach envisions that materials used in one building can be reclaimed and repurposed in new concrete after the original building reaches the end of its service life, while sequestrating CO2.
