METHODS FOR PRODUCING AIR-CURED FIBER CEMENT PRODUCTS

摘要

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 between about 5M % and about 40M % of said cured fiber cement powder; (c) Providing a green fiber cement sheet; and (d) Air-curing said green fiber cement sheet thereby providing an air-cured fiber cement product.
