Concrete is a widely used construction material that is exposed to various environmental influences during its service life, including changes in moisture content, temperature fluctuations, and chemical attack. These influences force it to address important durability issues, such as Alkali-Silica Reaction (ASR). ASR is a harmful reaction and mainly depends on temperature, moisture and alkali/silica content in concrete. Recently, many researchers have recognized the importance of ASR on concrete durability, and studies are being conducted to better understand the diagnosis, prognosis, and management of ASR. Therefore, the objective of this study is to investigate the ASR behavior of the prepared specimens at different curing temperatures and different water/cement ratios. To determine the effects of temperature and water-cement content on ASR, three different curing temperatures (40 °C, 60 °C, and 80 °C) and three different water-cement ratios (0.4, 0.5, and 0.6) were preferred in the study. The mentioned temperature and water content are the most important parameters affecting ASR formation, and it should be investigated how changing the amount of these parameters affects the behavior of reaction. During the study, the Accelerated Mortar Bar Test (AMBT) according to ASTM C1260 was used to measure the expansion of mortar bars. The differences in ASR behavior were revealed by the expansion results obtained.
