Abstract

In this paper, rust-protection performance of concrete using ground granulated blast-furnace slag are discussed. 4 kinds of W/B in combination with 3 kinds of replacement ratio of ground granulated blast-furnace slag and 2 kinds of chloride ion contents of are selected as experimental parameters. According to the experimental results, as the replacement ratio of ground granulated blast-furnace slag is increased, the corrosion area of steel bar tends to be decreased. However, as the autoclave cycle and chloride ion contents are increased, the corrosion area of steel bar is increased. In conclusion, when the replacement ratio of ground granulated blast-furnace slag is 50%, the strength and rust-protection performance appear to be most excellent.
