| 要旨 |
Autogenous healing of concrete structure was studied as a part of measures for reduction of the total life cycle cost. This study presents the measurement for autogenous healing ability by using the stiffness through three-point bending test. It shows the relation between autogenous healing ability and the initial loading age for three kinds of concrete, such as normal concrete, fly ash concrete and fly ash concrete with fiber. Furthermore, the size effect of specimens on autogenous healing is examined. |
