Abstract
This study aimed to evaluate the field feasibility of a newly developed ternary blended concrete mix and its effect on mitigating thermal cracking in massive concrete structures. Four mock-up test members were cast using different types of cementitious binders, and variations in temperature and strain with time were monitored for these members. Results showed that reduced heat of hydration in the ternary mix significantly diminished variations in temperature and strain in the test member. A crack survey revealed that the ternary mix reduced the extent of thermal cracking and tightened crack widths, indicating that it can be used to effectively control thermal cracks in massive concrete structures.
