INTRODUCTION
ROCK
It is a naturally occurring solid aggregate of minerals.
BASALT ROCK
It is an igneous rock formed from frozen lava. It occupies 1/3 of earth’s crust. Plentiful in Michigan’s upper peninsula. In India it occurs in deccan traps .
It is a material made from extremely
fine fibers of basalt, which is composed
of the minerals plagioclase, pyroxene,
and olivine.

BASALT SOURCES FORFIBER PRODUCTION
Temperature history and rate of cooling of
lava
• Slow cooling results in segregation and
precipitation
• Weathering and oxidation over-time
Chemical characteristics and uniformity of
basalt quarry are essential for good fibers.
Manufacturing should be close to suitable
basalt quarries and inexpensive energy.
SPINNING OF BASALT
FIBER Though basalt stones are available in
different compositions, only certain compositions and characteristics can be used for making the continuous filaments with a diameter range of 9 to 24 microns.
Compounds present in the basalt rock may vary, especially the SiO2 content depending on their nature and origin. Basalt rocks with SiO2 content about 46% (acid basalt) are suitable for fiber production.
BASALT QUARRY [ESSINGEN -EIFEL]
MANUFACTURING PROCESS OF BASALT FIBREQuarried basalt rock is first crushed,
then washed and moved into melting
baths in gas-heated furnaces. under
temperature of 1460-1500 °C. Here,
the process is simpler than glass fiber
processing because the basalt fiber
has a less complex composition.

BASALT FIBRE PRODUCTION
1. Tank for sizing
2. Furnace
3. Bushing
4. Sizing applicator
5.Tray for used sizing
collection
6. Winder
7. Spool
8. Tank for used sizing
Molten basalt flows from furnace through a
platinum-rhodium bushing with 200, 400 ,800 or
more holes and the fibers can be drawn from the
melt under hydrostatic pressure
A sizing is applied to the surface of the fibers by
a sizing applicator to impart strand integrity,
lubricity, and resin compatibility.
Finally, a winder allows to release some large
spools of continuous basalt filament.

BASALT CONTINUOUS
FIBERS Basalt Continuous Fiber (BCF) is a raw material for the
production of various types of materials & products.
APPLICATIONS
Reinforcing material for concrete & asphalt, concrete
covering for roads, airport runways & taxiways.
Filters for industrial & residential waste waters, filters
for smoke & dust emissions of industrial enterprises.
Reinforcing nets for construction.

BASALT PLASTIC PIPES
Basalt fiber composite pipes are obtained by
winding basalt threads, fabrics, prepegs
impregnated with a binder.
These pipes are useful as components for
shafts linings, building components, for
transporting corrosive liquids and gases in the
construction, industrial, agricultural and public
services sectors.
Basalt pipes are resistant to the action of fungi
and micro organisms.
BASALT PLASTIC PIPES
.
Great river energywear resistant basalt-lined piping extended
the reject piping’s life and reduced
maintenance requirements.
Basalt Lined Ash Disposal Pipes
BASALT SUPER THIN
FIBERS It has good heat-insulation qualities.
The material is absolutely nonflammable, it has
high thermo durability.
High chemical durability towards water, salt
solutions, alkali and acids.
APPLICATIONS :
Fireproof materials of fire protection systems
Heat and sound insulation material for the
manufacture of automobile mufflers, gaskets,
insulation screens, plastics, composites.

BASALT ROVING
Basalt roving is bundle of continuous mono
directional complex basalt fibers.
Roving possesses high natural strength,
resistance to aggressive environments, long
service life and excellent electric insulating
properties. APPLICATIONS: Filament winding of pipes,
tanks and cylinders
Reinforced plastics
Rewinding of primary string by machine from bobbins on basalt roving spool
Chopped basalt roving is mainly used as a substitute of fiberglass
FIELDS OF APPLICATIONS1.CONSTRUCTION:• Reinforcement of bridges,
tunnels.
• Internal waste pipes
• Repair of cracks, local damage to buildings & bridges.
2.PETRO CHEMICAL INDUSTRIES:
• Chemical & wear proof coverings of tanks.
• pipelines, oil pipelines.• nonflammable coverings &
composite materials.
Road construction
Petro chemical industries
3.AGRICULTURE:
Land drainage pipes, pipes for
irrigation and hosing.
4.MACHINE BUILDING:
Parts or blocks of machines
operating under high temperatures
or gas stream, For example the heat
shield for a re-entering space
vehicle.
5.ENGINEERING NETWORKS:
Oil and gas pipelines, pipes
for chemical products and
transportation of aggressive media.
High efficient seals & linings for pipelines.
Vertical roller mills has its applications in power plants & in chemical industry
Basalt road application
A distinctive feature of this rebar is high
corrosion resistance to aggressive
environments, namely to chloride salts, carbon
dioxide, nitrogen oxide.
It can even put uncoated chopped fiber
in concrete for crack resistance
High Strength compared to steel.
Light weight and flexibility makes installation
easier.

Retaining curb wall and concrete rebar before concrete has been poured
ADVANTAGES OF BASALT FIBER
Basalt fibers show 15-20% higher tensile strength and modulus.
Better chemical resistance.
Extended operating temperature range.
Better environmental friendliness.
Recyclability.
The processing of basalt fibers does not require special equipment or technologies.
DISADVANTAGES OF BASALT
FIBER
The price of fibers made from basalt is
higher than those made of E-glass.
The American Concrete Institute,
Canadian Standards Association,
International Federation for Structural
Concrete and other internationally
recognized engineering code authorities
have not provided specific design
guidance for its use.
1. Basalt fibers have excellent set of properties like Chemical Thermal Mechanical environmental 2.It can replace glass in large part is widely used in
aerospace, petrochemical, automative and other areas therefore basalt fiber is known as 21st
century “SILK VOLCANIC CHANGE”.As a result of its characteristics and
properties, basalt fiber can be really considered as the material of OUR FUTURE FOR A GREEN AND SUSTAINABLE DEVELOPMENT
