Title (EN) CEMENT ADMIXTURE, CEMENT ADDITIVE AND METHOD FOR PRODUCING MIXED CEMENT
(FR) MÉLANGE DE CIMENTS, ADDITIF POUR CIMENT ET PROCÉDÉ DE PRODUCTION D'UN CIMENT MÉLANGÉ
(JA) セメント混合材、セメント添加材、並びに混合セメントの製造方法
Abstract: front page image
(EN)Provided is a technology capable of transporting and storing fly ash to be used as a material for mixed cement, etc. without generating dust, and without using containing means such as an airtight silo, etc. After producing granulates which are hardened bodies of a composition composed of fly ash added with cement and water, the granulates are transported and stored. Further, the granulates preferably comprise gypsum and/or cement kiln dust. When using as a material for mixed cement or as a cement admixture, these granulates are pulverized to obtain fine powder having fly ash as the main ingredient.
(FR)La présente invention concerne une technique de transport et de stockage de cendres volantes à utiliser comme matériau pour ciment mélangé, etc., n'entraînant pas la génération de poussière et n'utilisant pas de récipients tels que des silos hermétiques, etc. Après la production de granulés, sous la forme de corps durcis, à partir d'une composition contenant un ciment et de l'eau auxquels des cendres volantes sont ajoutées, les granulés sont transportés et stockés. En outre, les granulés comprennent de préférence du gypse et/ou des poussières de four à ciment. Lors de leur utilisation comme matériau pour ciment mélangé ou comme mélange de ciments, ces granulés sont pulvérisés pour obtenir une poudre fine contenant, comme ingrédient principal, des cendres volantes.
(JA) 密閉性の高いサイロ等の収容手段を用いなくても、混合セメントの材料等として用いるためのフライアッシュを、発塵させずに輸送及び保管することのできる技術を提供する。 フライアッシュにセメント及び水を加えてなる組成物の硬化体である造粒物を製造した後、この造粒物を輸送及び保管する。この造粒物には、さらに、石膏及び/又はセメントキルンダストを含有させることが好ましい。混合セメントの材料としての使用時、または、セメント混和材としての使用時に、この造粒物を粉砕して、フライアッシュを主成分とする微粉末を得る。
