| Outline of Final Research Achievements |
Alkali silica reaction (ASR) that was one of the concrete degradation phenomena became an object of public concern 1983 years. The control measures are executed in 1986, and a reactive case is reported now. Therefore, the development of an easier, handier control method is hoped for, and it has been clarified that the method of adding a small amount of calcium propionate is experimentally examined, and there is a controlling effect.
In this study, the ASR controlling effect of calcium propionate was confirmed from the result of the experiment by a severe environmental condition that the environment, salt water, and the alkaline solution for a long-term outdoor weathering are supplied from the outside.
