3. INTRODUCTION
Concrete is a composite material with a low tensile strength and
a low strain limit.
The addition of fiber to the concrete mix can significantly
improve the engineering properties of the concrete.
Due to high corrosion resistance, high ductility and sufficient
durability, FRC is widely used.
Various types of fibers can be used in cement and concrete
composite, such as steel or organic fibers.
Basalt fiber is a new kind of inorganic fiber extracted from
melted basalt rock and is currently available commercially.

9. Ecological friendliness
•Basalt fibers have natural raw material, which is basalt rock it
does not cause any damage to the health.
•Basalt fibers has no biological hazards and solves waste
disposal problems.
•It does not clog incinerator as glass. Hence, it is incinerator
friendly.

14. APPLICATION OF BASALT FIBERS
REINFORCED CONCRETE
 Basalt has good electrical and sound insulating properties
and chemical resistance, especially in strong alkalis
Basalt composite pipes can be used to transport corrosive
liquids and gases.
Field application of basalt fiber reinforcement includes
concrete industrial concrete floors, runways in airport, motor
way, industrial floors, in shops where heavy equipment is used,
internal reinforcement of tunnels and channels, and military
installation.

15. ADVANTAGES OF BASALT FIBER REINFORCED
CONCRETE
Reduces the width of the cracks.
The total cost of the construction work reduces.
The fiber can be easily mixed.
The cost of repairs and maintenance greatly reduces due to
fiber reinforced concrete long life time.
The thickness of the concrete layer can be reduced to half.
Basalt fiber is not liable to galvanic corrosion, comparing to usual
rebar that is an electrical conductor and can have the cathode effect.

applications
• Building and construction: BFRC can be used in the
construction of buildings, bridges, and other
structures to improve their strength and durability.
• Infrastructure: BFRC can be used in the construction
of roads, sidewalks, and other infrastructure projects
to improve their longevity and resist damage from
heavy traffic and weathering.
• Industrial floors and pavements: BFRC can be used
in the construction of industrial floors and
pavements, such as in warehouses and factories, to
improve their durability and resistance to heavy
loads.

applications
• Marine structures: BFRC can be used in the construction of
marine structures, such as docks, piers, and breakwaters, to
improve their resistance to corrosion and damage from wave
action.
• Earthquake-resistant structures: BFRC can be used in the
construction of structures designed to resist damage from
earthquakes, due to its improved mechanical properties and
higher resistance to cracking.

19. CONCLUSION
The basalt fibers is now being popular choice for the material scientist for the
replacement of steel
and carbon fibers due to its high rigidity and low elongation or extension at
break.
Its supreme tenacity value makes it as a useful reinforcement material in the
present and also for the future era to come.
The most important contribution due to the addition of basalt fibers is the
change of mode of failure from a brittle to ductile, when subjected to
compression, bending, tension and impact with improvements in properties of
concrete specified in the catalogue provided by the supplier.
The basalt fiber rebar having full resistance against corrosion may be good
alternative for the reinforcement of concrete structures, like RC bridge girders
subjected to an environmental attack.
Finally we may concluded that the basalt fiber can be used as a good
alternative strengthening material instead of glass fiber, carbon fiber, steel fiber,
