FIBRE FOR DISPERSE REINFORCEMENT OF CONCRETE Russian patent published in 2016 - IPC E04C5/00 C04B14/38 

FIELD: construction.

SUBSTANCE: invention relates to construction. Fibre for disperse reinforcement of concrete is made in the form of a piece of a filament with anchors at the ends. Segment of the filament consists of two branches interconnected with a common anchor made with the possibility of changing the branches orientation relative to the common anchor. In one case the branches of the fibre can be turned in plane x-y around the center of the common anchor relative to each other with the turning angle of α=0°-90°, in the second case the branches of the fibre can be opened relative to each other in plane x-z, wherein the opening angle is β=0°-90°, and in the third case the branches of the fibre can be jointly (simultaneously) turned and opened relative to each other in plane x-y-z, herewith turning angle α is equal to angle of opening β and is 0°-45°.

EFFECT: technical result is higher structural strength of concrete.
