CEMENT CLINKER AND CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To sufficiently inhibit decrease in flowability of a cement composition comprising cement clinker even when AlOcontent in the cement clinker is relatively high.SOLUTION: The cement clinker according to the present invention comprises AlOof 6.0 mass% or more and 8.0 mass% or less, SOof 0.7 mass% or more and 2.2 mass% or less, and F of 0.01 mass% or more and 0.3 mass% or less, wherein the AlOcontent (mass%), the SOcontent (mass%), and the F content (mass%) satisfy the following formula 1: AlOcontent≤αSOcontent+β (where, α=10.3×F content+1.3, β=γ×F content+δ, γ=-13.0, δ=5.2)
【課題】セメントクリンカ中のＡｌ2Ｏ3が比較的多い場合にも、該セメントクリンカを含むセメント組成物の流動性の低下を十分に抑制することを課題とする。【解決手段】本発明のセメントクリンカは、Ａｌ2Ｏ3を６．０質量％以上８．０質量％以下、ＳＯ3を０．７質量％以上２．２質量％以下、Ｆを０．０１質量％以上０．３質量％以下含むセメントクリンカであって、前記Ａｌ2Ｏ3の含有量（質量％）と、前記ＳＯ3の含有量（質量％）と、前記Ｆの含有量(質量％)が下記式１を満たす関係である。Ａｌ2Ｏ3の含有量≰αＳＯ3の含有量＋β・・・（１）（但し、α＝１０．３?Ｆの含有量＋１．３、β＝γ?Ｆの含有量＋δ、γ＝−１３．０、δ＝５．２）【選択図】なし
