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
