The success of fibre cement manufactured by the Hatschek process is largely due its formation in thin paper like films that are placed one on the other until the desired sheet thickness is reached. Formation of the sheet by this means distributes the reinforcing fibres in two dimensions taking best advantage of the reinforcing fibres to increase the in-plane strength of the sheet.

Ludwig Hatschek biography, list of Ludwig Hatschek

About Inventor Ludwig Hatschek (1856 1914) began manufacturing asbestos board and asbestos gaskets (asbestos) in Vöcklabruck. In order to make the asbestos board hard so it can be used to produce panels, Hatschek experimented with various binding agents. The addition of Portland cement in 1900 led to the sought-after achievement.

formation on the Hatschek machine (Figure 3) by filtration of a dilute slurry of fibers and equidimensional sand and cement particles. This filtration process produces a film that is typically around 0.25 to 0.40 mm thick and each fiber cement sheet comprises a stack of these films. Thus, an 8 mm (5/16”) thick sheet will consist of between 20 to
