| Research Abstract |
A granulation technology of self-healing agent for crack self-healing concrete, which can repair cracks by itself was developed in order to retain the effect of self-healing agent in long time range. Self-healing agent is granulated by mixing with binder materials. This technology can restrain the contact possibility between self-healing agent and water during mixing and then the fresh property such as slump and flowability of concrete is not affected. Further, the crack self-healing capability can be maintained.
