The recycled glass fine aggregate (RGS) causes an alkali-silica reaction (ASR). Various supplementary cementitious materials (SCMs) can reduce ASR expansion of RGS. In this study, the mechanical properties after ASR of RGS mortar mixed with SCMs was evaluated. It was confirmed that the RGS mortar mixed with SCMs decreased ASR expansion. However, the mechanical properties after ASR decreased as reaction days increased. This is because ASR gel was formed inside the microcracks that existed in RGS. Therefore, the ASR gel inside the RGS destroyed the RGS and reduce the mechanical properties. |
