(57) The invention relates to processes for manufacturing monolith and precast fiberconcrete structure elements. The process for manufacturing non-homogeneous fiberconcrete structure elements comprises: preparation of mixture of concrete components - mineral components, water, additives (without fibers), placing it in a mold and its compaction. After that the precise amount of fibers is being uniformly strewn on the upper surface of the concrete and after that the...
