Despite the development of several self-healing concrete techniques, only micro cracks can be effectively self-repaired. To achieve self-healing of macro cracks (>1 mm), a strategy by in-situ calcium alginate crosslinking within cracks was proposed herein. This strategy was accomplished by encaps...
