Microcapsule-based intelligent resilience concretes are being widely recognized as a remedial technique to improve the durability of concrete. Microcapsule-based Intelligent Resilience in Concrete: Design, Performance and Evaluation provides an overview of the creation and further development of novel microcapsule-based self-resilience systems and their applications in concrete structures. The three comprehensive self-resilience systems - namely physical, chemical and bionic restoration systems - are discussed in detail: together with the major challenges regarding evaluation and future developments in self-resilience in concrete structures
- Provides a systematic overview of microcapsule-based intelligent resilience systems in concrete
- Discusses the design concept and preparation process for microcapsule-based intelligent resilience systems
- Includes detailed information on the self-healing mechanism and performance recovery of microcapsule-based intelligent resilience systems
