description	PROBLEM TO BE SOLVED: To provide a cement and a hydraulic composition which can be fired at low temperature, can increase an amount of an AlO-containing waste to be used, has better fluidity than conventional one, and has good strength development property.SOLUTION: There are provided a cement and a hydraulic composition in which the total amount of CA and CAF which are obtained by calculating a mineral composition of a clinker by Bogue equation is 24% or more, a CS amount is 60-63%, a CS amount is 8-11%, and an iron ratio (I.M) is 1.3 or less, and fluidity and strength development property are excellent. The hydraulic composition desirably has gypsum added thereto, and preferably contains 1-25% of limestone in the total composition.SELECTED DRAWING: None 【課題】低温で焼成することが可能で、Ａｌ２Ｏ３含有廃棄物の使用量も多くでき、かつ、従来よりもいっそう流動性が良好で、さらには強度発現性が良好なセメントや水硬性組成物の提供。【解決手段】クリンカーの鉱物組成をボーグ式により算出されたＣ３ＡおよびＣ４ＡＦの合計量が２４％以上、Ｃ３Ｓ量が６０〜６３％、Ｃ２Ｓ量が８〜１１％であり、かつ鉄率（Ｉ．Ｍ）が１．３以下とする流動性および強度発現性が良好なセメントや水硬性組成物。望ましくは、石こうが加られ、さらには、石灰石を全組成物あたり、１〜２５％含むことが好ましい、水硬性組成物。【選択図】なし
