Self-healing performance of intelligently building concrete module

Intelligent building concrete module is an important part of parametric construction and its self-repairing performance is the premise condition for ensuring the quality of the building. In this paper, some experiments have been done using fly ask, slag, meta-kaolin and silica fume mixed into cement in order to test several performances, including compressive performance, impermeability and self-healing performance. The results demonstrate: the worst healing effect was fly ash, followed by slag, meta-kaolin and silica fume. In the cement-based materials, the self-repair of the cracks mainly concentrated in the early production of cracks, so paid attention to the protection of the early maintenance is the key for self-repair effect.
