This research investigated fresh and hardened properties of concretes containing three different types of slag at three different replacement ratios and three different water/binder ratios. The three types of slag include ground granulated blastfurnace slag, ground granulated Corex slag and a ground granulated ferro-manganese arc furnace slag. The test results indicate that the use of the slags under investigation increases concrete workability at high water/binder ratios only. One-day strength values were strongly dependent on the slag replacement ratio. The influence of slag replacement level on compressive strength reduced over time. Notably, strength development characteristics and long-term strength values were considerably different for different types of slag.
