Basalt fiber reinforced concrete (BFRC) is a new kind of material that is
helpful in improving
the strength and durability of concrete.
In fact Basalt Fibre Reinforced Concrete is more durable than the Glass Fibre
Reinforced Concrete.
BFRC is sustainable because basalt is an abundant raw material and the
production process is environmentally friendly.

Properties of Basalt Fibre
Chemical Properties of Basalt Fibre
Basalt Fibre exhibits excellent alkali resistance.
The weight loss of Basalt Fibre in boiling water is less.
These fibres exhibits excellent resistant against acid and salt attack.

Properties of Basalt Fibre
Thermal Properties of Basalt Fibre
Basalt Fibre exhibits excellent thermal properties as like Glass Fibres.
Basalt Fibre can resist temperature as high as 1200 centigrade to 1300
centigrade easily for a long duration.
Unstressed Basalt Fibre can maintain their integrity upto 1250 Centigrade.

Properties of Basalt Fibre
Corrosion and Fungi Resistance
Basalt Fibre shows excellent corrosion resistance that on which we can rely on.
They don’t even undergo corrosion.
They shows the best resistance against fungi and bacterial attack.

Applications of 10
Basalt Fibre Reinforced
Concrete
BFRC is used in industrial floors, Airport Runways, Motor ways, and internal reinforcement
of tunnels and channels.
Basalt has good electrical and sound insulating properties. So it could be used in
auditoriams.
Basalt Composite pipes could be used in transporting corrosive liquids.

Advantages of the Basalt Fibre Reinforced Concrete
1) Reduces the width of cracks
2) We can make even thinner elements of concrete which is not
possible in case of RCC.
3) We can mix Fibres with other constituents of concrete.
4) Maintenance will be easy as the concrete has longer durability.
5) Basalt fibre is immune to galvanic erosion unlike to Steel Rebar
reinforcement.

Technical Advantages of use of Basalt Fibre as Reinforcement
1) Low level of Micro Cracks (up to 90%)
2) Increases Flexural Strength (Up to 35%)
3) Increases Concrete Fatigue Strength and Resistance (Up to 40%)
4) Increases the Frost Resistance (up to 35%)
5) Increases Water Tightness (up to 50%)
6) Increases surface endurance of concrete (up to 70%)
7) Decreases the slivering of Corners and Edges (Up to 90%)

Conclusion-
The adoption of Basalt Fibre Reinforced Concrete is finding its place in construction industry
Slowly but steady place.
At present the main challenge for Basalt Fibre Reinforced Concrete is its cost.
The manufacturing is not at scale and price is also high.
The failure of Concrete element reinforced with Basalt Fibre is ductile even when loading under
Compressive, shear, or bending loads.
Basalt Fibre Reinforced Concrete has potential to be prominent solution where concrete faces
Severe exposure.
We can also conclude that Basalt Fibre has advantage over Glass Fibre as reinforcement.
