可持续混凝土是当今建筑业面临的最大挑战之一。基于性能的混凝土规格可以在支持“可持续建筑”概念的同时，实质性地帮助应对这一新的挑战。混凝土几乎可以在每一种建筑结构中找到，无论是人行道、桥梁、房屋、隧道还是大坝。目前，学者们正在研究混凝土的最佳平衡配合比，以减少其对环境的影响，特别是以高碳排放著称的水泥成分。本文描述了混凝土的耐久性，并概述了哪些项目规范将显著影响混凝土的性能，包括其对环境的影响。本文认为，尽管混凝土具有可持续性，但仍需要科学家和工程师的共同努力来改进混凝土的设计，以确保其预期的可持续质量和可靠性。
Sustainable concrete is nowadays one of the biggest challenges in the construction industry. Performance-based specifications for concrete can materially help meet this new challenge while supporting the concept of “sustainable construction”. Concrete can be found in almost every building structure, be it a pavement, a bridge, a house, a tunnel or a dam. Scholars nowadays are researching the best balanced mix in concrete in order to diminish its environmental impact, especially the cement component which is known for its high carbon emissions. This paper describes concrete durability and outlines what project specifications will significantly influence concrete performance, including its environmental impacts. The paper argues that, despite the sustainability of concrete, concerted efforts on the part of scientists and engineers are still necessary to improve the design of concrete in order to ensure their expected sustainable quality and reliability.
