摘要： The present invention relates to processes and apparatuses for producing fiber cement sheets as well as fiber cement sheets obtainable therewith. The processes according to the present invention at least comprise the steps of: (a) providing a cementitious slurry comprising fibers, (b) continuously discharging the slurry on an endless water-permeable transport belt, and (c) removing excess of water from the slurry through the water-permeable transport belt to form a fiber cement sheet with a predetermined thickness. By using a water-permeable transport belt for removing the excess of water from the fiber cement sheet, both the thickness and the density of the sheet can be accurately tuned, without resulting in a spring-back of the thickness of the sheet at the end of the production process. The present invention further relates to various uses of the fiber cement sheets obtainable by the processes of the invention in the building industry.
