METHOD OF SORTING COAL ASH
PROBLEM TO BE SOLVED: To provide a method capable of easily sorting coal ash used for a coal ash-containing raw material for cement clinker high in easily burning property, based on physicochemical properties of coal ash.SOLUTION: The method of sorting coal ash is a method for sorting coal ash used for a coal ash-containing raw material for cement clinker high in easily burning property, based on a B value calculated from the following (1) formula. B=S/A+0.058×C (1), where S represents percentage content (mass%) of SiOin a glass phase in coal ash, A represents percentage content (mass%) of AlOin the glass phase in coal ash and C represents Blaine specific surface (cm/g) of the coal ash.SELECTED DRAWING: Figure 2
【課題】本発明は、石炭灰の物理化学的特性に基づき、易焼成性の高いセメントクリンカー用石炭灰含有原料に用いる石炭灰を、簡易に選別できる方法を提供する。【解決手段】本発明の石炭灰の選別方法は、下記（１）式から算出されるＢ値に基づき、易焼成性の高いセメントクリンカー用石炭灰含有原料に用いる石炭灰を選別する方法である。Ｂ＝Ｓ／Ａ＋０．０５８×Ｃ ・・・（１）ただし、（１）式中、Ｓは石炭灰内のガラス相中のＳｉＯ２の含有率（質量％）を表し、Ａは石炭灰内のガラス相中のＡｌ２Ｏ３の含有率（質量％）を表し、Ｃは石炭灰のブレーン比表面積（ｃｍ２／ｇ）を表す。【選択図】図２
