Long-Term Characteristics of High-Strength Concrete Using Finely Ground Granulated Blast Furnace Slag

Abstract

In this study, long-term strength characteristics and durability of high-strength concrete using ground granulated blast furnace slag fine powder with specific surface area of 12000 and 16000 cm 2 /g were researched. As a result, the concrete using finely ground granulated blast furnace slag has the same strength properties and carbonation depth at 20 years, as concrete using silica fume. From the experimental results, it is revealed that finely ground granulated blast furnace slag can be used as an alternative material for silica fume to product high-strength concrete.
