Abstract

This paper presents a comprehensive investigation regarding the carbonation, chloride ions penetration and freeze-thaw durability test of Reactive Powder Concretes (RPCs). Experimental results demonstrate that the depth of carbonization deepens in RPCs with the extension of carbonization time, but the internal carbonization reaction gradually weakens. The wetting-drying cycles accelerates chloride ion migration in concrete. Freeze-thaw cycles reduce the mechanical properties of concrete.
