Abstract
This article presents a literature review concerning the durability of self-compacting concrete (SCC), making a comparison between this new type of concrete and the vibrated concrete (VC). The degradation mechanisms that have been considered are: carbonation, chloride penetration, sulphate attack, frost durability and salt scaling, and fire resistance. The carbonation of SCC is not significantly deviating from the carbonation of VC. Cyclic wetting and drying in a chloride containing solution shows significantly lower chloride diffusion in SCC in comparison with VC. The initiation time for sulphate attack is prolonged in SCC compared with an equivalent VC due to a denser microstructure in SCC. Frost action in combination with de-icing salts is leading to similar mass losses in SCC as in VC. SCC has a high probability of spalling when exposed to fire even in a dry environment, so precautions shall be taken when SCC shall be used in situations where no fire spalling is accepted.
