CEMENT CLINKER AND CEMENT
PROBLEM TO BE SOLVED: To provide a cement clinker that can suppress the volume change after hardening of a cement-containing hardened body.SOLUTION: Provided is a cement clinker having a percentage content of 2CaO-SiO, as a value calculated by the Bogue equation, of 30 to 60 mass% as well as having a percentage content of 3CaO-AlOof less than 6 mass%, and in which the percentage content of SOin said cement clinker is 0.30 mass% or less. The percentage content of MgO in the cement clinker preferably is 1.50 mass% or more.SELECTED DRAWING: None
【課題】セメント含有硬化体の硬化後の体積変化を抑制することができるセメントクリンカを提供する。【解決手段】ボーグ式で算出される値として、２ＣａＯ・ＳｉＯ2の含有率が３０〜６０質量％でかつ３ＣａＯ・Ａｌ2Ｏ3の含有率が６質量％未満であるセメントクリンカであって、該セメントクリンカ中のＳＯ3の含有率が０．３０質量％以下であるセメントクリンカ。該セメントクリンカ中のＭｇＯの含有率は、好ましくは１．５０質量％以上である。【選択図】なし
