摘要

Capsules (2) for reinforcing fibrous concrete and comprising the individual fibers (1) formed as coiled elements and the solid wrappers (4) made of a water-soluble glue and enclosing said coiled elements. Method of the production of the capsules (2), wherein first the individual fibers (1) are prepared as coiled elements whereupon each individually coiled fiber is enclosed in the wrapper made of a water-soluble glue and the capsules are let dry up. The method of the production of the fibrous concrete is then characterized in that the aforesaid capsules (2) are dispensed into the dry concrete mixture or aggregates and the subsequent dry intermixing of the same is followed by the addition of batch water.
