HYDRAULIC COMPOSITION AND CONCRETE USING THE HYDRAULIC COMPOSITION

摘要

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.
