Although PE substitutions increased the permeable porosity and sorptivity, it significantly improved the sulfate resistance of SCC.The influence of PE shape and size on workability and strength was found to be more important than its type.Because of the different mix design in comparison with traditional concrete and the abscence of vibration, different characteritics can be expected for self-compacting concrete (SCC). Shah (Ed.), Challenges and barriers to application : proceedings of SCC 2008 (pp. Presented at the 3rd North American conference on the Design and Use of Self-Consolidating Concrete : Challenges and barriers to application (SCC 2008), Center for Advanced Cement-Based Materials. Hydration, microstructure, transport properties and durability of self-compacting concrete. Challenges and barriers to application : proceedings of SCC 2008. The degradation mechanisms of a cementitious material are greatly influenced by the permeability of the material for potentially aggressive substances. Hydration, microstructure, transport properties and durability of self-compacting concrete.

This was used to compare the potential diffusivity of different concretes.

The results indicated that SCC, for both grades of strength, made with PFA showed much lower diffusivity values in comparison with other mixtures, whereas the SCC mixtures with VMA showed higher diffusivity.

This study reports the findings from an investigation carried out to study the effect of the mixture variations on the durability of medium- and high-strength self-consolidating concrete (SCC).
