Description and Properties

“FIBER-PLUS” polypropylene microfibre by BAYRIS is an innovative polymer product offering the following advantages: approximately 250,000,000 fibres per 1 kg; improved frost resistance and waterproofing performance of concrete; enhanced tensile and impact strength of concrete; minimised shrinkage and prevention of cracking. “FIBER-PLUS” by BAYRIS is a polypropylene reinforcing fibre designed to improve the physical, mechanical and performance characteristics of reinforced concrete structures and construction mortars. The product does not damage construction equipment or tools and is compatible with all concrete and mortar additives (plasticisers) by BAYRIS.

“FIBER-PLUS” polypropylene fibres (microfibre) are used in the production of all types and grades of concrete for residential and industrial construction. Suitable for paving slabs (block paving), blind areas, concrete slabs and foam concrete production. Ideally suited for use in underfloor heating systems. Polypropylene fibre can also be used in waterproof plastering mortars, cement-sand screeds and monolithic wall casting.

Product Preparation and Application

Product preparation: if stored or transported at sub-zero temperatures, the product must be conditioned at a temperature of at least +5 °C for no less than 12 hours before use.

Dosage: dosing of “FIBER-PLUS” microfibre by BAYRIS does not require specialised equipment or tools. It is recommended to add the microfibre at the initial stage of mixing. For improved dispersion, the microfibre may be added to the mixing water.

Mixing: “FIBER-PLUS” microfibre by BAYRIS can be mixed manually or mechanically using gravity or forced-action mixers. The microfibre must be thoroughly mixed until the fibres are evenly distributed throughout the mass. Approximate mixing time at the recommended dosage: up to 7 minutes (manual mixing), up to 3 minutes (mechanical mixing), until uniform distribution is achieved when added to ready-mix concrete or mortar.

Characteristics: fibre length (mm) – 12. Single fibre diameter (μm) – 20. Chemical resistance to acids, alkalis and solvents – complete resistance. Modulus of elasticity (N/mm², minimum) – 3500. Tensile strength (N/mm², minimum) – 400. Melting point (°C) – 160. Colour – translucent white, milky white.

Consumption: 0.6–0.9 kg/m³: cement-sand screeds, concrete paths, blind areas, construction mortars, plaster, foam concrete, polystyrene concrete, decorative gypsum and concrete cast products;

0.9–1.8 kg/m³: underfloor heating systems, parking areas, outdoor platforms, roads (light traffic load);

1.8–2.4 kg/m³: hydraulic structures.

ATTENTION!

Safety measures: follow general safety and hygiene regulations. The use of personal respiratory protective equipment is recommended.

FAQ
What Is Microfibre?

The word “fibra” originates from Latin and means “fibre”. Microfibre consists of polypropylene reinforcing fibres designed to improve the physical, mechanical, and performance properties of reinforced concrete structures and construction mortars used in both residential and industrial construction.

What Types of Fibre Reinforcement Are Available?

A wide range of fibre reinforcement solutions is available on the market. The most common types, classified by material, include: steel fibre, basalt fibre, glass fibre (composite), polyester fibre, and polypropylene fibre (polymeric).

Polypropylene fibre is the most widely used type of reinforcing fibre and is the most popular choice worldwide.

Why Is Polypropylene Microfibre the Best Choice?

Microfibre is used for dispersed reinforcement in concrete and mortars. Dispersed reinforcement involves distributing a large number of individual fibres throughout the concrete or mortar mix. An important requirement is that the fibres must remain chemically stable and not react with the cementitious matrix. A fibre length of 12 mm is the most widely used, as fibres longer than 18 mm generally become less effective due to the significantly lower number of fibres contained within each kilogram.

FIBER-PLUS™ by BAYRIS features a fibre length of 12 mm and is fully resistant to acids and alkalis. Its high melting point, excellent modulus of elasticity, and strong tensile properties make polypropylene fibre a reliable and proven reinforcement material that has been used worldwide for more than 40 years. The combination of these characteristics provides significant advantages over many alternative micro-reinforcement solutions.

In addition, polypropylene fibre offers several important technical advantages over basalt and glass fibres. These include a substantially higher fibre count per kilogram, complete resistance to both acids and alkalis, and improved distribution throughout the mix. Unlike some alternative fibres, polypropylene fibres do not tend to clump together or settle in the lower layers of concrete or mortar, as their density is close to that of water. These properties help ensure more uniform reinforcement and improved long-term performance.

What applications is microfibre used for?

FIBER-PLUS™ by BAYRIS is suitable for use in all types and grades of concrete. It is particularly well suited for underfloor heating systems and can be used in the production of paving blocks, kerbs, concrete slabs, and foamed concrete. Polypropylene fibre may also be incorporated into water-resistant rendering mortars, cement-sand screeds, and monolithic concrete wall construction.

Why Add Microfibre to Concrete and Mortars?

The use of FIBER-PLUS™ Reinforcing Fibres by BAYRIS helps prevent cracking in concrete and reduces shrinkage. The product improves tensile strength and impact resistance, while also enhancing the frost resistance and water tightness of concrete.

Is Microfibre Compatible with Plasticisers?

FIBER-PLUS™ Microfibre by BAYRIS is compatible with all BAYRIS admixtures for concrete and mortars and does not cause damage to construction equipment or tools.

Can Microfibre Replace Steel Mesh and Reinforcement?

Even among construction professionals, there is sometimes a misconception that microfibre can completely replace structural reinforcement, such as reinforcing bars in load-bearing concrete elements. However, this is not the case. Microfibre is used for dispersed reinforcement, the purpose of which is to improve crack resistance, impact strength, and reduce shrinkage, rather than to increase the load-bearing capacity of a structure, as conventional steel reinforcement does.

In many screed and floor applications, polypropylene microfibre may be used as an alternative to traditional shrinkage-control steel mesh. However, the suitability of such a solution should always be assessed according to the project requirements and the designer’s specifications.

How Do I Choose Microfibre Reinforcing Fibres?

When choosing microfibre reinforcing fibres, we recommend considering the following factors:

- Is the microfibre manufactured from 100% virgin raw materials?

- Does one kilogram contain more than 200 million microfibres?

- Is the fibre material resistant to acids and alkalis?

- Is there proven international experience of using this type of microfibre?

- Is this type of microfibre used in industrial construction projects?

If you are interested in FIBER-PLUS™ by BAYRIS, the answer to all of the above questions is yes. Choose with confidence.
