Permeation properties of self-compaction concrete

    Research output: Chapter in Book/Report/Conference proceedingChapter

    Abstract

    This chapter attempts to provide an updated review on the permeation properties of SCC. Available experimental results on permeation properties of various SCC mixes in comparison with conventional vibrated concretes of a similar strength grade were analysed. As expected, the most important factors influencing the permeation properties of SCC mixes appeared to be: w/c ratio, degree of hydration and mineral additions. Due to the refined pore structure and denser ITZ observed, SCC mixes generally showed significantly lower gas permeability and water sorptivity, compared to conventional vibrated concrete of the same strength grade. The chloride ion diffusivity of the SCC mixes appeared to be significantly influenced by the total pore volume (or porosity). At similar w/c ratio and strength grade, the SCC mixes with significantly greater paste volume showed significantly higher chloride ion diffusivity than the corresponding conventional vibrated concrete mixes.
