Abstract:
This committee investigated the mechanism and modeling of the creep, drying shrinkage. autogenous shrinkage, and durability of quasi-brittle friction materials including cement -based materials and structural concrete, with the aim of improving the methods of estimating volume changes and proposing the methods of their application. The activities of the committee included research into the following: (1 ) clarification of the relationship between the nano pore structures and accuracy improvement of creep and drying/autogenous shrinkage of concrete; (2) comparison and accuracy improvement of creep and drying/autogenous shrinkage estimation models; and (3) systematization of deterioration phenomena affecting the durability of concrete from the mechanical aspect.
