| Abstract |
It is very important to start and maintain the curing of concrete at the early age in hot weather environment. Therefore, this study was conducted to investigate the effect of curing by reviewing the ...various characteristics according to curing method in order to control the quality of floor slab concrete under hot weather environment. Concrete curing was performed through three kinds of method: water spray curing, sheet curing and non-curing. Especially in the case of water spray curing, the start time of watering was set different. As the result of experiments, Even if floor slab concrete is manufactured in hot weather, the temperature of concrete did not rise significantly in comparison with column concrete specimen. In addition, Experiment results indicate that water spray curing is effective on the compressive strength, neutralization and air permeability. On the other hand, the characteristic difference of floor slab concrete according to curing method was not significant under standard weather environment. In addition, it was confirmed that the water curing within a few hours of placing is effective in order to satisfy both the strength and durability of concrete under hot weather environment.show more
