Abstract

Air void structure plays a key role in the durability of concrete structures in cold regions. This is because water in the microstructure can escape into the air voids which, thereby, effectively reduce the stresses during cyclic freezing and thawing. This protects the concrete structures from developing frost damage [1, 2]. Therefore, to assure the frost resistance of conventional concrete, it is necessary to quantify its air void structure.
