To provide a biomass ash granule for effectively utilizing biomass ash as an alternative material of an aggregate, while suppressing an increase of a chlorine content ratio of a cement mix, a cement mix, and a manufacturing method of the cement mix.SOLUTION: Biomass ash granules have preferably a value of a cumulative volume percentage of a particle size distribution of 10% (D10) of 35 μm or larger, furthermore, a content of chlorine (Cl) of 0.1 mass% or smaller, a content of amorphous of 60 mass% or smaller. A method for producing the cement mix is characterized that the method comprises a process of classifying the biomass ash into coarse powder and fine powder (a) and a process (b) of mixing the coarse powder obtained in the above step (a) into cement and water without pulverizing it.SELECTED DRAWING: Figure 2 【課題】セメント混練体の塩素含有率の上昇を抑制しつつ、バイオマス灰を骨材の代替材料として有効に活用するためのバイオマス灰粉粒物、セメント混練体、およびセメント混練体の製造方法を提供する。【解決手段】バイオマス灰粉粒物は、粒度分布の累積体積百分率が１０％の値（Ｄ１０）が３５μｍ以上であり、さらに、塩素（Ｃｌ）の含有率が０．１質量％以下であり、非晶質の含有率が６０質量％以下であることが好ましい。セメント混練体の製造方法は、バイオマス灰を粗粉と細粉に分級する工程（ａ）と、前記工程（ａ）で得られた前記粗粉を、粉砕することなくセメント及び水に混合する工程（ｂ）とを有することを特徴とする。【選択図】図２
