由于城市化和世界人口的增加，对水泥和混凝土的需求正在高度增长。波特兰水泥生产向大气中排放了大量温室气体，这是导致气候变化的原因。此外，水泥和混凝土行业消耗大量能源和自然资源。因此，重要的是开发新的方法来克服这些产品带来的挑战。本文的目的是对实现水泥混凝土行业可持续发展的机遇进行回顾。用辅助胶凝材料部分替代水泥，是减少混凝土中水泥用量的主要途径之一。本文还综述了其他可以提高水泥和混凝土行业可持续性的因素，包括利用再生骨料和其他再生材料、优化混凝土配合比设计、结构优化、替代化石燃料、碳捕获和储存、提高混凝土的耐久性、延长现有基础设施的使用寿命、水管理、执行法规以及碳化、替代粘结剂、储能和能量收集等其他机会。这些解决方案可以在生产更可持续的混凝土方面发挥重要作用，从而减少温室气体排放、节约自然资源、减少废物和节约能源。
The demand for cement and concrete is highly increasing due to urbanization and increase in the world’s population. Portland cement production releases substantial amounts of greenhouse gases (GHGs) into the atmosphere, which is causing the climate change. Furthermore, cement and concrete industries consume a large amount of energy and natural resources. Therefore, it is important to develop new methods to overcome the challenges created by these products. The purpose of this paper is to make a review of opportunities for achieving sustainable cement and concrete industry. Using supplementary cementitious materials as partial replacement of cement, is one of the main opportunities to reduce the amount of cement usage in concrete. The paper also reviews other factors that can increase sustainability of cement and concrete industry, which include utilizing recycled aggregates and other recycled materials, optimize concrete mix design, structural optimization, replacement of fossil fuels, carbon capture and storage, increasing durability of concrete, extending the service life of existing infrastructures, water management, implementing regulations as well as other opportunities such as carbonation, alternative binders, energy storage and energy harvesting. These solutions can play an important role in producing more sustainable concrete and thus, reducing GHG emissions, conserving natural resources, decreasing wastes and conserving energy.
