Abstract
Asbestos-free fiber reinforced hydraulically setting materials, which comprise a slurry of one or more hydraulic binding agents, fibers, water and perhaps additional additives, are obtained when, as fiber, 2 to 20% by volume of filter fibers and 0,5 to 20, preferably 1 to 10% by volume reinforcing fibers are used, both of which are subjected to preliminary treatment which improves their dispersability. By means of the preliminary treatment the fibers can be uniformly distributed in the slurry. The material can be worked on apparatus common for the production of asbestos cement and used for the same purposes as asbestos cement.
