3.3 Cellulose fibers

Fibers made of cellulose are used as additives in building products to enable the dispersion of synthetic fibers in the cement matrix.

An example for the application of cellulose fibers which is under development is a so-called fiber cocktail, consisting of cellulose and cellulose fiber acting to disperse polyvinylalcohol or polyacrylnitrile fibers in the cement matrix (Eternit AG). Through special processing procedures, an orientation of the fibers is also achieved, which leads to an improvement in the mechanical properties.
