FIBRE FOR DISPERSED REINFORCEMENT OF CONCRETE Russian patent published in 2023 - IPC E04C5/03 

FIELD: construction.

SUBSTANCE: fibre for dispersed reinforcement of concrete belongs to the field of construction, in particular to artificial fibre for reinforcing building products. The fibre for dispersed reinforcement of concrete is made in the form of segments of two twisted wires with the formation of free ends. The free ends form end anchors and are made bent relative to each other in the shape of a dovetail. Pairs of end anchors can be rotated 90° relative to each other. Between two twisted wires, when they move apart, at least two cells can be formed, which are rotated relative to each other by 90°.

EFFECT: increase in the structural strength of concrete, rigidity and increase in the volume of micro-reinforcement.
