Les b\u00e9tons \u00e0 hautes performances pr\u00e9sentent une durabilit\u00e9 am\u00e9lior\u00e9e et une r\u00e9sistance accrue. Ils sont capables de supporter des charges sup\u00e9rieures ou permettre des constructions plus \u00e9lanc\u00e9es. Les B\u00e9ton \u00e0 Haute Performance peuvent \u00e9galement pr\u00e9senter des formes plus complexes et permettent de r\u00e9aliser des ouvrages de grandes port\u00e9es. Pendant sept jours nous avons conserv\u00e9 dans l\u2019eau des \u00e9prouvettes cylindriques de b\u00e9ton pour tester la r\u00e9sistance, \u00e0 sept jours d\u2019\u00e2ges, du b\u00e9ton \u00e0 haute performance formul\u00e9. Ce choix a \u00e9t\u00e9 guid\u00e9 par un souci de maitrise de la formulation des B\u00e9ton \u00e0 Haute Performance d\u2019une part et de v\u00e9rification de sa r\u00e9sistance \u00e0 son jeune \u00e2ge d\u2019autre part.<\/p>\n

L\u2019objectif vis\u00e9 a aussi guid\u00e9 le choix des param\u00e8tres retenus pour la formulation et les essais\u00a0tels que la granulom\u00e9trie\u00a0; l\u2019affaissement du b\u00e9ton et la r\u00e9sistance \u00e0 la compression.<\/p>\n

Les r\u00e9sultats montrent que les b\u00e9tons \u00e0 hautes performances ont une r\u00e9sistance \u00e0 la compression beaucoup plus \u00e9lev\u00e9e.<\/p>\n
