¿ä¾à2 This research explores a refined approach to mitigating the setting time delays encountered in thixotropic cement-based materials. The study evaluated three alkali agents?potassium hydroxide, sodium hydroxide, and calcium hydroxide?along with a chemical accelerator, to determine their effectiveness in addressing the delay. The results revealed that, aside from calcium hydroxide, the alkalis and the accelerator showed promising outcomes in reducing setting time. However, increasing the dosages of potassium hydroxide and sodium hydroxide negatively impacted the thixotropic properties of the paste. In contrast, the accelerator demonstrated a unique ability to preserve and even enhance thixotropy with higher dosages. Therefore, the findings suggest that the accelerator is a more effective and reliable solution than alkali materials for resolving setting time delays in thixotropic cement systems
