The Hatschek process of manufacturing fiber cement was an innovation made by the famous Austrian Ludwig Hatscheck in the early years of 1890. The process was a resultant of seven tedious years of cellulose experimentation of reinforcing the fibers using cement in water. The combination of cement, cellulose fibers and water (slurry) ended up in ...

 · The flocculation process is important in the Hatschek process when fiber-cement is produced. This is due to its influence on mineral fines retention, and on the dewatering rate of the thin fiber-cement sheets in the sieve rotating in contact with the suspension in the vat, which affects machine productivity and, as a consequence, the product ...

 · 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
