Title (EN) HYDRAULIC COMPOSITION AND CONCRETE USING THE HYDRAULIC COMPOSITION
(FR) COMPOSITION HYDRAULIQUE ET BÉTON UTILISANT LA COMPOSITION HYDRAULIQUE
(JA) 水硬性組成物および該水硬性組成物を用いたコンクリート
Abstract: front page image
(EN)Disclosed is a hydraulic composition that can provide a concrete having a strength comparable with the strength of a high-strength concrete or an ultra-high-strength concrete despite the fact that the composition has a low cement content or does not contain cement. Also disclosed is a concrete using the hydraulic composition. The hydraulic composition comprises 10 to 40% by weight, based on the whole composition, of at least one of cement and slaked lime. The content of the cement and the content of the slaked lime each are not more than 20% by weight of the whole composition. The hydraulic composition comprises 40 to 90% by weight in total, based on the whole composition, of fly ash and a fine powder of blast furnace slag. The content of the fly ash is not less than 15% by weight of the whole composition. The hydraulic composition optionally comprises silica fume, anhydrous gypsum and the like.
(FR)La présente invention concerne une composition hydraulique qui peut donner un béton ayant une résistance comparable à la résistance d’un béton à hautes performances ou d’un béton à ultra-hautes performances en dépit du fait que la composition a une faible teneur en ciment ou ne contient pas de ciment. L’invention concerne également un béton utilisant la composition hydraulique. La composition hydraulique comprend 10 à 40 % en poids, sur la base de la composition entière, d’au moins un ciment ou une chaux éteinte. La teneur en ciment et la teneur en chaux éteinte ne dépassent pas 20% en poids de la composition entière. La composition hydraulique comprend 40 à 90% en poids en tout, sur la base de la composition entière, de cendres volantes et d’une poudre fine de scorie de haut fourneau. La teneur en cendres volantes n’est pas inférieure à 15% en poids de la composition entière. La composition hydraulique comprend facultativement de la fumée de silice, du gypse anhydre et similaires.
(JA) セメント量が少ない、またはセメントを含まないにもかかわらず、高強度コンクリートまたは超高強度コンクリートに相当する強度のコンクリートが得られる水硬性組成物および該水硬性組成物を用いたコンクリートを提供する。 水硬性組成物において、セメントおよび消石灰のいずれか一種以上を全体の10~40重量%配合する。セメントおよび消石灰の含有量は各々全体の20重量%以下とする。また、フライアッシュと高炉スラグ微粉末を合計で、全体の40~90重量%配合する。フライアッシュの配合量は全体の15重量%以上となるようにする。さらに、必要に応じシリカヒューム、無水石膏などを配合する。
