Throughout the mix
Fibers are distributed during mixing.
Basalt fiber
Tiny strands. Added while the concrete is mixed.

For small cracks
The effect depends on the mix and dosage.
Mix-specific dosage
Determined for your particular concrete.
Where it is used
Near water and the coast
Tanks, coastal structures and concrete exposed to moisture and salts. Mesh suitability for the environment is checked; fiber is evaluated for crack control.
Roads and slabs
Slabs, pavements and infrastructure elements. Mesh and fiber selection depends on loads, design and service conditions.
Floors and parking areas
Floors, yards and parking areas exposed to impact and wear. Dispersed reinforcement requires a confirmed mix design and appropriate tests.
Easier on site.
Savings go beyond the material price.
Added to the mix
Fibers are added during mixing at the specified dosage.
Throughout the volume
Distributed through concrete. They do not automatically replace structural reinforcement.
Potential for lower total cost
We compare material, delivery and labor for your project. A lower total price is possible, but requires a design and a specific quotation.

More questions?
What is basalt fiber?
Short basalt strands introduced into the concrete mix. Unlike mesh, they do not form a prefabricated panel or sit at one specified level within the element.
How does it act in concrete?
Distributed fibers can bridge small cracks and help limit their development. The effect depends on length, quantity, bond with the matrix and even distribution.
Where can it be considered?
Pavements, industrial floors and slabs where crack control, flexure or impact matter. The application is evaluated with a project mix design and appropriate tests.
How is it added to the mix?
Agree the addition sequence and mixing time with the concrete technologist and product instructions. Check even distribution, workability and pumping suitability; fiber clumps are undesirable.
How is dosage determined?
Dosage in kg/m³ is validated for the formulation and objective. Percentages in the supplied laboratory table are not a commercial dosage. The calculator below uses an already approved dosage.
What should an enquiry include?
Concrete type, application, total volume, crack or mechanical requirements and placing conditions. Include the dosage and fiber length requirements if a mix has been approved.
Tests and sources
Tests: compare the results
The source table concerns cement specimens with 10 mm long, 40 μm diameter fibers. The measured property is flexural tensile strength, not concrete compressive strength.
Control without fiber12 MPa
Fiber specimen24 MPa

2%, 3% and 4% are experimental mass fractions as reported in the source. The percentage basis and full protocol are not specified. This is not a dosage recommendation in kg/m³.

How much material do I need?
Fiber is measured in kilograms per cubic metre of concrete. The right amount depends on the mix and the result you need. Once it is confirmed, use the calculator to work out the total.
Calculate fiber quantity
This calculates quantity, not a dosage. Experimental mass percentages are not automatically converted to kg/m³.
