摘要

混凝土的自愈是材料自身修复内部裂缝的过程。这个过程可以通过自体或自主愈合来产生。自体愈合是一个自然过程，由碳酸化和/或持续的水合作用产生。自主愈合是基于使用特定的药物来产生自我修复，这些药物可以直接添加到混凝土基质中，嵌入胶囊中或通过血管网络引入。一些例子是高吸水性聚合物、结晶外加剂、微胶囊硅酸钠和细菌。本综述分为两部分。第一部分是自愈混凝土的概述，总结了自愈混凝土的基本概念和近年来的主要进展。第二部分是对自愈混凝土的可行性、其可能性、当前的弱点以及未来几年需要解决的挑战的关键讨论。

Self-healing concrete-What Is it Good For?

Self-healing of concrete is the process in which the material regenerates itself repairing inner cracks. This process can be produced by autogenous or autonomous healing. Autogenous healing is a natural process, produced by carbonation and/or continuing hydration. Autonomous healing is based on the use of specific agents to produce self-healing, which can be added directly to the concrete matrix, embedded in capsules or introduced through vascular networks. Some examples are superabsorbent polymers, crystalline admixtures, microencapsulated sodium silicate, and bacteria. This review is structured into two parts. The first part is an overview of self-healing concrete that summarises the basic concepts and the main advances produced in the last years. The second part is a critical discussion on the feasibility of self-healing concrete, its possibilities, current weaknesses, and challenges that need to be addressed in the coming years.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
