| 要旨 | The mechanism of alkali-silica reaction (ASR) in concrete induced by sodium salts released from radioactive waste materials was investigated. The expansion behavior of mortar bars immersed in sodium sulfate and sodium phosphate was compared. ASR occurred for specimens in sodium sulfate solution. ASR did not occur for specimens immersed in sodium phosphate solution. Hydroxy-apatite, which is a hard and dense compound was formed in the surface layer of the specimens and therefore, no expansion was observed, regardless of solution concentration. |
