Strength and Durability of Concrete with Blast Furnace Slag

The properties of concrete using blast furnace as binder and fine aggregate have been investigated in this study. The experiments focus on the properties of concrete such as compressive strength and young's modulus, carbonation, diffusion of chloride ions, resistance to sulfate attack and resistance to freeze and thaw. The experimental results show that when blast furnace slag is used in concrete, it improves the durability properties of concrete. However, the combination of using both blast furnace slag as binder and fine aggregate shows a greater improvement of those properties of concrete.
