Title: Effect of Condensed Silica Fume on the Diffusion of Chlorides through Hardened Cement Paste
Author(s): Olav Gautefall
Publication: Special Publication

Keywords: cement content; cement pastes; chlorides; diffusivity;
fly ash; hardened paste structure; silica; water-cement ratio.
Abstract:This report presents the results of the diffusivity of chloride ions in hardened cement paste. The experiments were carried out at 20°C and both ordinary portland cement and blended cement with 10% fly ash have been investigated. Other experimental variables were water-to-(cement + condensed silica fume) ratio of 0.5, 0.7 and 0.9. The condensed silica fume was used as a cement replacement, the replacement levels being 5.10 and 15% by weight of cement.
