Title (EN) METHODS FOR PRODUCING AIR-CURED FIBER CEMENT SHEETS
(FR) PROCÉDÉS DE PRODUCTION DE FEUILLES DE FIBROCIMENT DURCIES À L'AIR
Abstract:
(EN) The present invention relates to methods for the production of air-cured fiber cement products. More particularly, the present invention provides methods for the production of air-cured fiber cement products, at least comprising the steps of: (a) Providing cured fiber cement powder by comminuting cured fiber cement material; (b) Providing an aqueous fiber cement slurry comprising water, cementitious binder, natural or synthetic fibers and said cured fiber cement powder; (c) Providing a green fiber cement sheet; (d) Pressing said green fiber cement sheet; and (e) Air-curing said compressed fiber cement sheet thereby providing an air-cured fiber cement product.
(FR) La présente invention concerne des procédés de production de produits de fibrociment durcis à l'air. Plus particulièrement, la présente invention concerne des procédés de production de produits de fibrociment durcis à l'air, les procédés comprenant au moins les étapes suivantes : (a) utilisation d'un fibrociment durci réduit en poudre par broyage ; (b) utilisation d'une suspension aqueuse épaisse de fibrociment comprenant de l'eau, un liant cimentaire, des fibres naturelles ou synthétiques et ledit fibrociment durci réduit en poudre ; (c) préparation d'une feuille de fibrociment crue ; (d) pressage de ladite feuille de fibrociment crue ; et (e) durcissement à l'air de ladite feuille de fibrociment après compression, pour obtenir ainsi un produit de fibrociment durci à l'air.
