| Research Abstract |
The present study examined the method of adding a small amount of calcium propionate with the effect of decreasing the alkali as an easy control method of the alkali aggregate reaction (ASR) of a concrete degradation phenomenon. The experiment method observed the reaction situation by making a concrete test piece using the reactive aggregate that added the calcium propionate, and setting it up in the reactive promotion environment and the outdoor exposure environment in the laboratory. As a result, the test piece that adds the calcium propionate has understood the reaction of ASR is controlled.
