Abstract

The unique technology was developed to control the hydration heat of mass concrete by adding the Phase Change Material(PCM) to concrete. The PCM was designed to liquefy at 60 degrees and its size was limited under $10{\sim}30$ micro meters to be put in pores and to have no effect on compressive strength. In the hydration heat test, center temperature of the PCM specimen was reduced by 10 degrees without any difference in the strength. Even in the adiabatic temperature rise test, the final adiabatic temperature rise amount was reduced as much as 25% in comparison with the standard value in Korean Concrete Standard Specification.
