混凝土可持续发展:应对碳排放引起气候变化危机

Sustainable Development of Concrete: Tackling the Climate Change Crisis Caused by Carbon Emissions

混凝土是人类文明在地球上有形足迹的最明显表现之一, 其应用量大面广, 已成为世界上用量最大的人造工程材料。混凝土改变了世界并塑造了人类文明, 在未来仍然不可或缺。但大量混凝土的生产和使用对资源、能源和环境影响巨大, 是全球碳排放重要来源之一。基于大气中二氧化碳浓度导致气候快速变化而威胁人类生存条件的预测, 为推动人类社会和文明的永续发展, 混凝土发展面临严峻挑战。本文首先简要介绍了混凝土的基本知识, 其次总结了混凝土的发展历程, 再次分析了混凝土发展目前面临的挑战, 最后提出了混凝土可持续发展的策略与路线。

As one of the most visible manifestations of the tangible footprint of human civilisation on the planet, concrete is largely and widely applied, and has become the most widely used man-made engineering material in the world. Concrete has changed the world and shaped human civilization, and will remain indispensable in the future. However, as one of the major sources of global carbon emissions, the production and application of large quantities of concrete has a huge impact on resource, energy and the environment. Based on the prediction that the rapid climate change, caused by the concentration of carbon dioxide in the atmosphere, will threaten the living conditions of human beings. Thus, the development of concrete is facing serious challenges in order to promote the perpetual development of human society and civilization. This paper firstly introduces the basic knowledge of concrete briefly, then summarizes the development history of concrete, analyzes the challenges of concrete development at present, and finally puts forward strategies and routes for the sustainable development of concrete.
