Abstract

ABSTRACT Self-healing is recognized as a promising technique for increasing the durability of concrete structures by healing cracks, thereby reducing the need for maintenance activities over the service life and decreasing the environmental impact. Various self-healing technologies have been applied to a wide range of cementitious materials, and the performance has generally been assessed under ‘ideal’ laboratory conditions. Performance tests under ideal conditions, tailored to the self-healing mechanism, can demonstrate the self-healing potential. However, there is an urgent need to prove the robustness and reliability of self-healing under realistic simulated conditions and in real applications before entering the market. This review focuses on the influence of cracks on degradation phenomena in reinforced concrete structures, the efficiency of different healing agents in various realistic (aggressive) scenarios, test methods for evaluating self-healing efficiency, and provides a pathway for integrating self-healing performance into a life-cycle encompassing durability-based design.

自修复混凝土技术在现实条件下用于耐久和可持续混凝土的效率综述

摘要自修复是一种很有前途的技术，可以通过修复裂缝来提高混凝土结构的耐久性，从而减少使用寿命内的维护活动，减少对环境的影响。各种自修复技术已应用于各种胶结材料，其性能通常在“理想”的实验室条件下进行评估。根据自我修复机制，在理想条件下进行性能测试，可以证明自我修复的潜力。然而，在进入市场之前，迫切需要在现实模拟条件下和实际应用中证明自修复的稳健性和可靠性。这篇综述的重点是裂缝对钢筋混凝土结构退化现象的影响，不同愈合剂在各种现实（激进）场景中的效率，评估自修复效率的测试方法，并为将自修复性能整合到基于耐久性的生命周期设计中提供了一条途径。图形摘要
