In order to assess the compressive behavior of high performance concrete (HPC) that incorporates
ground granulated blast-furnace slag (GGBS) and silica fume (SF), uniaxial compression tests were carried
out in this study. For compressive strengths of HPC, three variable water-to-binder ratios (0.40, 0.34, and
0.28) were considered. Compressive strengths of the 100 mm x 200 mm cylinder specimens were
determined in accordance with KS F 2403 The compression strength at each curing age (1, 7, 28, and 91
days) was measured to evaluate the strength development characteristic of HPC under different curing
temperature (20, 35, and 50℃). Test results showed that the effect of curing temperature on the strength
development of concrete increased as water-binder ratio higher provided that developed strength is lower
67% of the specified compressive strength. However, in the stage of strength beyond 67% of the specified
compressive strength, the strength development rate wend slow down as the curing temperature higer.
Therefore, in the initial curing stage, high curing temperature is needed to accelerate the strength
development rate, and the proper curing temperature between 20℃ ~ 35℃ is required for controlling the
strength development rate of concrete.
