| 要旨 | This paper investigated the effect of exposure conditions specified in the ASTM C1260 on alkali-silica reaction (ASR) performance of ordinary Portland cement (OPC) and alkali-activated slag (AAS) mortars. The results showed that the expansion of OPC mortars are more affected by the exposure condition than AAS mortars, and the final expansion of AAS mortars are lower than that of OPC mortars after 56 days exposure in different conditions. SEM/EDS analysis illustrated that the (Na+K)/Si and Al/Si ratio of ASR products in AAS mortars is higher than that of OPC mortars. |
