Effect of Hydration Temperature Rise Inhibitor on the Temperature Rise of Concrete and Its Mechanism. [PDF]
Materials (Basel), 2023 The rapid drop in internal temperature of mass concrete can readily lead to temperature cracks. Hydration heat inhibitors reduce the risk of concrete cracking by reducing the temperature during the hydration heating phase of cement-based material but may reduce the early strength of the cement-based material.

Effect of Microencapsulated Temperature Rise Inhibitor on the Temperature Rise of Medium-Sized Concrete. [PDF]
Materials (Basel)This study investigates the effect of microencapsulated temperature rise inhibitors (TRIs) on the hydration temperature evolution and crack resistance of medium-sized concrete structures. Unlike mass concrete, medium-sized concrete elements such as beams, slabs, and columns pose unique challenges in temperature control due to their moderate volume ...
