Abstract
(EN)
Provided are: a fly ash in which reduction in fluidity thereof can be inhibited and the workability thereof can thereby be improved, and the occurrence of color unevenness thereof can be inhibited; a cement composition using the fly ash; and a production method for the fly ash. This fly ash is characterized in that the contained amount of particles having a particle size of 45 μm or more as measured by a laser diffraction scattering particle size distribution measurement method is less than 38 vol%, and the contained amount of particles having a particle size of less than 5 μm as measured by the aforementioned measurement method is 12 vol% or less. This cement composition contains said fly ash and cement.
(FR)
L'invention concerne : des cendres volantes dans lesquelles une réduction de fluidité correspondante peut être inhibée et la maniabilité correspondante peut ainsi être améliorée et l'apparition d'une irrégularité de couleur correspondante peut être inhibée ; une composition de ciment utilisant les cendres volantes ; et un procédé de production pour les cendres volantes. Ces cendres volantes sont caractérisées en ce que la quantité contenue de particules présentant une grosseur de particule de 45 µm ou plus, telle que mesurée par un procédé de mesure par diffusion/diffraction laser de la distribution des grosseurs de particule, est inférieure à 38 % en volume et la quantité contenue de particules présentant une grosseur de particule inférieure à 5 µm, telle que mesurée par le procédé de mesure susmentionné, est de 12 % en volume ou moins. Cette composition de ciment contient lesdites cendres volantes et du ciment.
