Abstract
The durability of a cementitious material is greatly influenced by the permeability of the material for potentially aggressive substances. As the pore structure of self compacting concrete (SCC) might be different in comparison with traditional concrete (TC), some changes in durability behaviour may occur. At this moment however, it is unclear how significant these differences will be with regard to the concrete practice. In this paper, the gas and water transport in SCC with limestone filler or fly ash is investigated experimentally. Nine different concrete compositions are considered: one TC and eight SCC mixtures. Some important parameters like the water/cement (W/C) and cement/powder ratio (C/P), type of filler (limestone filler and fly ash), type of aggregate and type of cement are considered. The results of the gas and water transport are discussed and linked to experimental data concerning pore volume. Lower transport properties can be obtained by using fly ash instead of limestone as filler material, by lowering the W/C ratio, decreasing the C/P ratio at a constant W/C ratio or using blast furnace slag cement instead of portland cement. The effect of changing from gravel to crushed limestone is small. SCC is differing strongly of TC with respect to the apparent gas permeability. This difference is probably due to the differences in pore volume, as seen from MIP results.
Résumé
La durabilité d’un matériau cimentaire dépend largement de sa résistance à l’intrusion d’espèces potentiellement agressives. Dû au changement de la composition du béton auto-plaçant (SCC) comparé à celle du béton traditionnel (TC), le système poreux et par conséquent la durabilité pourront être differents face au béton traditionnel. Au moment il n’est pas sûre comment cela va influencer l’emploi du béton à la pratique. Dans cet article les résultats obtenus expérimentalement concernant le transport de gaz et d’eau dans le béton auto-plaçant au filler sont analysés. Neuf gâchées de béton ont été préparées, représentant un béton traditionnel et huit bétons auto-plaçants. Les essais ont été realisés afin d’étudier l’influence de quelques paramètres : le rapport eau/ciment (W/C), le rapport ciment/poudre (C/P), le type de filler (filler calcaire où␣cendres volantes), le type d’agrégats et le type de ciment. Les résultats concernant le transport de gaz et d’eau ont été liés aux résultats expérimentaux de la porosimétrie au mercure. Il est possible de réduire le transport dans le béton en remplaçant le filler calcaire par des cendres volantes, en réduisant le rapport W/C, en augmentant le rapport C/P où en utilisant un ciment laitier de haut-fourneau au lieu du ciment Portand. Peu de différence peut être noté concernant la variation du type d’agregats. Une différence significative néanmoins est déterminée pour la permeabilité apparente de gaz entre le béton auto-plaçant et traditionnel. La différence pourrait être expliquée par la différence en volume des pores des bétons.
