This study is intended to examine the curing effect of the combination of the bubble sheet on the concrete by analyzing the temperature profile and core strength of the simulated concrete structure. The test results relvealed that the average temperature of the concrete applying photothermal sheet overlapped with the double bubble sheet at the bottom was 23.5℃, which had the highest insulation and insulation effect compared to other types of surface insulation curing sheets, and the core strength increased by up to 56%.

Due to the increase in the usage of explosive materials and terrorism, the interest towards the superior explosion protective HPFRCC has risen. In existing research, the optimum ratio for solving the problematic problems such as the optimum fiber incorporation rate and the self-shrinkage crack of HPFRCC had been derived. However, there had been few or even no research upon how effective HPFRCC would perform protective explosion-proof in actual explosion. Therefore, this research compared the explosion-proof performance of HPFRCC according to fiber commination and mixing ratio. As a result, the combination of steel fiber and organic fiber showed excellent flow and strength, and it also improved the explosion resistance.
