Previous studies have confirmed that applying thermal stimulation to Superplasticizers improves fluidity and instantaneous mixing without adversely affecting hardening properties. Therefore, this study investigated the effects of varying BFS levels on the freshness and hardening characteristics achieved by utilizing byproducts as thermal stimuli, and confirmed the thermal stimulation effect when utilizing supernatant. The results confirmed that adding BFS improved both fluidity and instantaneous mixing performance under thermal stimulation. However, it was also confirmed that the thermal stimulation effect became less pronounced as the amount of BFS increased. Furthermore, while improvements in fluidity and instantaneous mixing performance were confirmed even when using supernatant water, it was also confirmed that the thermal stimulation effect was less pronounced compared to when using tap water. It was also confirmed that thermal stimulation combined with the use of byproducts does not adversely affect the hardening properties.
