description	To provide a powder containing ground cement clinker, which is a cement material that has excellent early strength development under a low-temperature environment and shows a small degree of decrease in the early strength development when compared with the early strength development under a normal temperature environment.SOLUTION: A powder containing ground cement clinker is a cement clinker powder or a mixture of a cement clinker powder and a quicklime powder. The powder is composed of 42-65 mass% of alite, 12-40 mass% of belite, 12-18 mass% of aluminate phase, 0.5-12 mass% of ferrite phase and 0.7-3.0 mass% of free lime as calculated by the Borg formula where a value of the percentage of CaO used in the calculation of alite is the percentage of total CaO contained in the powder containing ground cement clinker, from which the percentage of free lime is subtracted.SELECTED DRAWING: None 【課題】低温の環境下において早期強度発現性に優れ、かつ、常温の環境下における早期強度発現性と比較した場合に早期強度発現性の低下の程度が小さいセメントの材料である、セメントクリンカ粉砕物含有粉末を提供する。【解決手段】セメントクリンカ粉砕物、または、セメントクリンカ粉砕物と生石灰粉末の混合物である、セメントクリンカ粉砕物含有粉末であって、ボーグ式（ただし、エーライトの算出において用いられるＣａＯの割合の数値は、セメントクリンカ粉砕物含有粉末に含まれる全ＣａＯの割合から、遊離石灰の割合を減じたものとする。）で算出される値として、エーライトの割合が４２～６５質量％、ビーライトの割合が１２～４０質量％、アルミネート相の割合が１２～１８質量％、および、フェライト相の割合が０．５～１２質量％であり、かつ、遊離石灰の割合が０．７～３．０質量％であるセメントクリンカ粉砕物含有粉末。【選択図】なし
