FIELD: chemistry.
SUBSTANCE: additive including zinc-twisted strands twisted into a bundle with a right Z-twist is described, in the form of a strip, by extruding a melt of a mixture of polypropylene-PP and low pressure polyethylene-LPPE, where the twisting is performed at a number of 40-45 twists per one running meter of fibre at a ratio components of the mixture, wt %: PP 67-73, LPPE 27-33 with additional subsequent corrugation of the said fibre. The invention is developed in dependent claims of the invention formula.
EFFECT: bulk reinforcement of cement products with high strength characteristics.
