摘要： The present invention relates to fiber cement flooring products. In particular, the present invention provides fiber cement flooring products, at least comprising cement and fibers, characterized in that these fiber cement flooring products comprise amorphous silica in an amount of between about 2 weight % and about 15 weight % compared to the total dry weight of the fiber cement composition of said fiber cement flooring product. The present invention further relates to methods for the production of such fiber cement flooring products as well as uses of such fiber cement flooring products in the building industry. The present invention further relates to fiber cement formulations and fiber cement materials, which are suitable for the production of fiber cement products for flooring applications.

摘要： The present invention relates to methods for the production of fresh cured fiber cement products. More particularly, the present invention provides methods for the production of fresh fiber cement products comprising cured fiber cement waste material, at least comprising the steps of: (a) Providing a cured fiber cement waste powder by comminuting cured fiber cement waste material; (b) Providing an aqueous fiber cement slurry comprising water, cementitious binder, natural or synthetic fibers and said cured fiber cement waste powder; (c) Forming a green fiber cement sheet from said aqueous fiber cement slurry; and (d) Autoclave-curing said green fiber cement sheet thereby providing a fresh fiber cement product.
