Ciment — Wikipédia
Le broyage a pour but de réduire les grains du clinker en poudre, et de permettre l’ajout du gypse (environ 4 %) et éventuellement d'autres adjuvants pour réguler quelques propriétés du ciment Portland, comme son temps de prise et de durcissement À la sortie du broyeur, le ciment est à une température environ de 160 °C, et avant dS'ajoutent à cela les divers frais de promotion et de marketing; dans le cadre de l'étude du MOTif, plusieurs éditeurs estimaient que ces frais correspondaient à 3 ou 4 % du prix de vente, bien que ces coûts variaient significativement d'un éditeur à l'autre [58] Enfin, les frais bancaires représenteraient entre 3 et 6 % du prix de venteLivre numérique — Wikipédia
