Abstract
(EN) Provided is a technique that enable effective utilization of biomass ash while inhibiting a reduction in the strength of a produced cured cement product. This method has: a step (a) for classifying biomass ash into rough powder and fine powder; and a step (b) for adding the rough powder obtained in step (a) at least to a cement clinker raw material to be put into a cement kiln, to a cement clinker obtained from the cement kiln, or to a cement obtained after a process of pulverizing the cement clinker.
(FR) L'invention concerne une technique qui permet une utilisation efficace de cendre de biomasse tout en inhibant une réduction de la résistance d'un produit de ciment durci produit. Ce procédé comprend : une étape (a) de classification de cendre de biomasse en poudre grossière et en poudre fine ; et une étape (b) d'ajout de la poudre brute obtenue à l'étape (a) au moins à une matière première de clinker de ciment destinée à être introduite dans un four à ciment, à un clinker de ciment obtenu à partir du four à ciment, ou à un ciment obtenu après un processus de pulvérisation du clinker de ciment.
(JA) 生成されるセメント硬化物の強度低下を抑制しつつ、バイオマス灰を有効に活用できる技術を提供する。 この方法は、バイオマス灰を、粗粉と細粉に分級する工程(a)と、工程(a)で得られた粗粉を、セメントキルンに投入されるセメントクリンカ原料、セメントキルンから得られたセメントクリンカ、又はセメントクリンカを粉砕処理後のセメント、の少なくともいずれかに投入する工程(b)とを有する。
