Premco MacroFiber Technical Data

Premco Constructional MacroFiber

REPLACEMENT OF STEEL FIBER, STEEL MESH

INCREASE OF CONCRETE TENSILE STRENGTH IN BENDING

REDUCTION OF CRACKING

Constructional polymer macro-fiber. Adding this fiber into the concrete mix increases its ability to distribute loads throughout the volume of the structure evenly, and absorb the internal energy of destruction.

IT Affects

INCREASES TENSILE STRENGTH IN BENDING
□ REDUCES SHRINKAGE WHILE CONCRETE
HARDENING
□ INCREASES THE RESIDUAL STRENGTH
(AFTER CRACKS FORMATION)
□ INCREASES PLASTICITY OF DESTRUCTION
□ REDISTRIBUTES BREAKING LOADS
□ INCREASES CRACKING RESISTANCE
OF CONCRETE CONSTRUCTIONS
□ REMOVES THE RISK OF CORROSION
□ ALLOWS TO GET RID OF CONSTRUCTION
REINFORCEMENT WITH STEEL MESH
□ INCREASES FIRE RESISTANCE
OF CONCRETE CONSTRUCTION
□ SAFER, EASIER AND CHEAPER
TO WORK THAN STEEL

Economic Applicability

To achieve the same results of strength of the slab, it is enough to use 6-6.5 times less polymer fiber than steel fiber.

Usage

Premco structural macrofiber can be added to concrete mix at any time before the application of concrete. It is generally recommended to add any fibrous material at a concrete plant during dosing. Fibers must be mixed with concrete for a minimum of three (3) to five (5) minutes with a maximum mixing speed, depending on the type of mixer to ensure complete dispersion and constancy. Add other impurities regardless
of the fiber added. Synthetic microfiber Premco is compatible with all additives.

Dosage

The dosage rate will vary depending on the requirements for reinforcing concrete and for providing equivalent tensile and bending resistance. The recommended dosage range for Premco Macrofiber is 2 to 8 kg/m3. When used in the proper dosage, Premco is an option to replace steel shrink mesh, and metal fiber or significantly reduce steel bar reinforcement. It is a safe and easy-to-use alternative reinforcement system that is resistant to corrosion and alkali.
