V12-AM
For slabs and slabs
13mm AR micro fiberglass
Highest zirconium content worldwide


FIBRATEC V12-AM is the alkali resistant fiberglass with the highest Zirconium content worldwide. This fiber is added to concrete to replace the mesh (electrowelded mesh) placed in the upper third in the construction of slabs.

These are fiber strands, made up of 100 filaments of 13.5 microns in diameter and cut to 13mm in length, perfectly calculated to obtain high-performance results. In turn, these filaments have been joined together with an advanced chemical adhesive (H950), to achieve the adequate integrity of the strands after they are weathered into the concrete during the mixing process in the tank of the truck or plant. of concrete.

It provides speed, simplicity and quality, eliminating all labor and thus avoiding accidents and cuts caused by handling the mesh during cutting and placement on site.

Fibratec V12-AM also saves money on transport and storage since it can be transported in the trunk of any vehicle in the formats of 1kg water-soluble bags or 20kg bags.

  • INCREASES THE RESISTANCE AT FIRST BREAKING BY BENDING BETWEEN 5 AND 20% WITH THE ADDITION BETWEEN 1 AND 3 KG / Mᶟ
  • INCREASES THE DURABILITY OF THE CONCRETE
  • IMPROVES RESISTANCE TO SURFACE ABRASION
  • DRASTICALLY DECREASES MICROFISSURING

How can you achieve it?

The School of Engineering at the University of Birmingham has shown that with the addition of just 2 kg of Fibratec V12-AM it is able to achieve the following improvements in an H25 concrete. (C25: 25 MPa compression):

  • CARBONATION: -47%
  • AIR PENETRATION: -87%
  • WATER PENETRATION: -58%
  • CAPILLARY ABSORPTION CAPACITY: -38%

The V12-AM micro fiber forms a network of hundreds of millions of fibers in a three-dimensional shape whose tensile breaking strength is greater than that of steel (1620N / mm2 vs 1200N / mm2), with a totally homogeneous distribution (specific weight of the fiber similar to that of concrete) and with a subjection to the spectacular concrete matrix carried out by the calcium hydroxide crystals that are produced during the chemical process of setting and curing the concrete, improving its resistance with each passing year. (The concrete curing process takes several years. Unlike steel fibers that lose reinforcement over time due to oxidation, the passage of time improves the strength of Fibratec AR glass fibers)

All these factors mentioned so far achieve a much less porous, more intense concrete, a concrete brought to its perfection thanks to the fact that the fibers have greatly hindered the loss of water in the mass, favoring the activation of all the cement motes in its interior and sewing the micro fissures inherent to the stresses produced within the concrete at the very moment of its appearance.

A mesh is not capable of providing any of the aforementioned benefits and for this reason it can be perfectly substituted for FIBRATEC V12-AM.

Adding, Mixing And Packing:

Mix in a concrete plant or truck mixer at a maximum speed of 15 r.p.m. ALWAYS AS THE LAST COMPONENT.

Add at a rate of 3 kg per minute. After all of the fiber has been added, allow an additional minute of mixing.

TOTAL PALLETIZED:

440 kg pallets in 20 kg bags, pallet measures 110x110x110cm.

We carry out technical dosing reports without obligation to justify substitution of mesh for fibers in projects for the facultative direction.

We must NEVER pretend to substitute metallic reinforcement with fibers of any kind in elements with structural requirements. (Load-bearing walls, columns, beams, mesh that are part of the structural calculation of compression layers …)

IMPORTANT NOTE:

Use concrete of the HA-25 or HA-30 type, preferably. All good concrete practices must be strictly enforced.

All dosing data are based on fibred concrete tests in Arco Tecnos laboratories in collaboration with the Almunia de Doña Godina Polytechnic University School.

All applications in past experiences in which the products have been applied and handled correctly, the results have been 100% satisfactory. 4.5 million square meters with mesh successfully replaced until 2020.

Actual application conditions may differ from laboratory conditions due to applicator circumstances. A concrete screed is the result of many components, circumstances and professional know-how, so the advice given does not give rise to any guarantee or legal obligation regarding its final effectiveness.

FIBRATEC CAN ONLY GUARANTEE THE QUALITY OF THE FIBER AND ITS CHARACTERISTICS.

DO NOT CONFUSE TRADITIONAL POLYPROPYLENE FIBERS WITH FIBRATEC V12-AM

MULTIFILAMENT POLYPROPYLENE FIBER

It helps to avoid micro-cracking caused by the sudden drying of the concrete, retaining the water in the mix and acting like a sponge.

Unfortunately, it does not guarantee an effective work because it is not distributed evenly in the concrete mass due to its specific weight very different from that of concrete. (0.9 gr / cm³ versus 2.4gr / cm³). As a result, we can observe many places without any fiber and others with excess fiber and floating on the surface forming nasty balls and lumps.


It cannot substitute a mesh in a screed and it is recommended to use it together with a shoe mesh to complement it.


Dries the concrete causing the addition of water and consequent weakening of its final strength and favoring micro-cracking.


Melting temperature: 173ºC


Leaves hairs on the surface, causes the formation of balls and lumps, making it difficult to polish, print or apply other additives.


It is sold in 600 gr water-soluble paper bags

MULTIFILAMENT POLYPROPYLENE FIBER

It sews the hundreds of millions of micro cracks produced by the entire mass of the concrete at the very moment of its appearance thanks to its homogeneous distribution and its high resistance to breaking by traction. (specific weight similar to that of concrete, 2.68 gr / cm³ vs. 2.45gr / cm³).

This immense network of fibers in all the heights of the thickness of the slab hinders the loss of water by all the layers of the slab equally, favoring the hydration of the cement.

IT EXTENDS THE USEFUL LIFE OF THE CONCRETE IN ADDITION TO GETTING AS AN ADDITIONAL BENEFIT RAISING THE FIRST-BREAKING STRENGTH OF THE CONCRETE TO BENDING.


It replaces the mesh shoe in the upper third of the sills.


It does NOT require adding water to the concrete because it does not absorb water.


Melting temperature:> 1500 ° C. Suitable for high temperature applications.


The surface is excellent without a trace of fibers and ready to polish, print and add any additive. It disperses with total homogeneity throughout the concrete mass in minutes.
