混凝土是一种不断发展的材料，甚至高性能混凝土的定义也随着时间的推移而发生变化。在本文中，混凝土材料的高性能特性被认为是那些支持直接影响我们生活质量的民用基础设施理想的耐用性、弹性和可持续性的特性。有人提出高性能材料特性包括拉伸延展性、自生裂纹宽度控制和材料“绿色”。此外，智能功能应旨在通过响应结构周围环境的变化来增强基础设施的耐用性、弹性和可持续性，以执行所需的功能，从而使材料的行为方式更类似于某些生物材料。基于工程水泥基复合材料（ECC）的最新进展，本文建议可以设计体现这种高性能特性和智能多功能性的混凝土，并具有满足 21 世纪预期民用基础设施需求的潜力。重点介绍了 ECC 的相关特性，并指出了未来必要的研究方向。
Concrete is a continuously evolving material, and even the definition of high-performance concrete has changed over time. In this paper, high-performance characteristics of concrete material are considered to be those that support the desirable durability, resilience, and sustainability of civil infrastructure that directly impact our quality of life. It is proposed that high-performance material characteristics include tensile ductility, autogenous crack-width control, and material “greenness.” Furthermore, smart functionalities should be aimed at enhancing infrastructure durability, resilience, and sustainability by responding to changes in the surrounding environment of the structure in order to perform desirable functions, thus causing the material to behave in a manner more akin to certain biological materials. Based on recent advances in engineered cementitious composites (ECCs), this paper suggests that concrete embodying such high-performance characteristics and smart multifunctionalities can be designed, and holds the potential to fulfill the expected civil infrastructure needs of the 21st century. Highlights of relevant properties of ECCs are provided, and directions for necessary future research are indicated.
