Outline of Final Research Achievements

The method of securing the initial quality of a concrete structure for the purpose of reservation of the durability of a concrete structure was established. The research for control the initial crack of concrete was carried out for the temperature crack and the drying shrinkage crack.
Prediction of occurrence of the temperature crack was established using the temperature stress analysis and the database of concrete construction record in a real structure. The technology developed by this research is utilized for revival of concrete structure which was destroyed by the East Japan great earthquake.
