ABSTRACT:
The invention relates to a process for the preparation of fiber-reinforced cement-based hydraulically hardenable shaped objects, which comprises spraying matrix and fibers with a spraying apparatus onto a deflecting surface to produce a mixture of matrix and fibers, removing the mixture in the unhardened state from the deflecting surface into a mould, and preparing from the mixture fiber-reinforced cement-based hydraulically hardenable shaped objects.
The invention further relates to an apparatus for the preparation of the above described shaped objects.
