BASALT ROCK FIBRE (BRF)

Rainbow BASALT ROCK FIBRE (BRF)
Basalt is well known as a rock found in virtually every country round the world. Basalt Rock fibres have no toxic reaction with air or water, are non-combustible and explosion proof. When in contact with other chemicals they produce no chemical reactions that may damage health or the environment. Basalt base composites can replace steel and known reinforced plastics (1 kg of basalt reinforces equals 9.6 kg of steel). There seemed to be something quite poetic in using a fibre made from natural rock to reinforce a material, which might quite reasonably be described as artificial rock. Raw material for producing basalt fibre is a rock of the volcanic origin. Fibres are received by melting basalt stones down at the temperature of 1400?C. Melted basalt mass passes through the platinum bushing and is extended into fibres. Basalt Rock fibre special properties reduce the cost of products whilst improving their performance. Scope: Low cost, high performance basalt fibres offer the potential to solve the largest problem in the cement and concrete industry, cracking and structural failure of concrete.Basalt fibre reinforced concrete could become the leading reinforcement system in the world for minimizing cracking, reducing road wear, improving concrete product life, lowering maintenance and replacement costs, and minimizing concrete industry law suits. It was therefore with considerable interest that use of basalt fibres as a reinforcing material for concrete. We propose here to investigate the usage of Basalt fibers in low cost composites for civil infrastructure applications requiring excellent mechanical support properties and long lifetimes. Because of the higher performance (strength, temperature range, and durability) and lower potential cost predicted for basalt fibers, they have the potential to cost effectively replace fiberglass, steel fiber, polypropylene, polyethylene, polyester, aramid and carbon fiber products in many applications.

BASALT ROCK FIBRE
NEW CONSTRUCTION TECH. & MATERIAL



BASALT

Basalt is well known as a rock found in virtually every country round the world. Basalt Rock fibres have no toxic reaction with air or water, are non-combustible and explosion proof.
Basalt base composites can replace steel and known reinforced plastics (1 kg of basalt reinforces equals 9.6 kg of steel).



SCOPE

Low cost, high performance fibres offer the potential to solve the largest problem in the cement and concrete industry, cracking and structural failure of concrete.
BECAUSE OF THE HIGHER PERFORMANCE (STRENGTH, TEMPERATURE RANGE, AND DURABILITY) AND LOWER POTENTIAL COST PREDICTED FOR BASALT FIBERS, THEY HAVE THE POTENTIAL TO COST EFFECTIVELY REPLACE FIBERGLASS, STEEL FIBER, POLYPROPYLENE, POLYETHYLENE, POLYESTER, ARAMID AND CARBON FIBER PRODUCTS IN MANY APPLICATIONS.


ADVANTAGES OF BASALT ROCK FIBERS:

1. They have no toxic action with air & water.
2. Very high chemical resistance.
3. Basalt is the best reinforcement for concrete due to its tensile strength
4. Noise absorption qualities
5. Basalt based composites can efficiently replace steel and all known reinforced plastics.
7. Water absorption
8. Melting temperatures & Working temperatures up to 600ºC.



FIELD APPLICATION OF BASALT ROCK FIBRE:

Construction
Road Construction
Underground Construction
Engineering Network
Agriculture



BASALT ROCK FIBRE PRODUCTS:

Basalt Reinforcement Rod
Continuous Basalt Fibre
Basalt Geotextile
Basalt reinforcing mesh



1 Basalt Reinforcement Rods:

Advantages Basalt rod over Steel rebar:
Higher specific strength
Resistant to corrosion
coefficient of thermal expansion
No permanent deformation when bent
Chemically inert


Application of Basalt Reinforcement Rod


3 Continuous Basalt Fibre:
ADVANTAGED OF CBF TECHNOLOGIES

1. Only one component “ basalt, which is an enviromently safe natural material “ is used for CBF production;
2. Cost of basalt raw material is very low; the share of raw materialâ„¢s cost in the final cost of production is less than 5%;
3. CBF production technology consists of only one phase “ melting. There is no need for primary enrichment, fusion and homogenization, as all of those were made for free by nature;
4. To make CBF basalt should be heated up only one time;
5. Further processing of CBF into materials does not require energy; itâ„¢s made with application of cold technologies".


4. Basalt reinforcing mesh

Basalt reinforcing mesh is designed for reinforcing road and highway overlays to prolong the pavement lifespan by reducing the effects of reflective cracking caused by traffic loading, age hardening and temperature cycling. Pavement life between maintenance can be prolonged significantly. Basalt reinforcing mesh makes it possible to reduce thickness of asphalt concrete pavement up to 20%.


Advantages and benefits

1.Higher mechanical strength and modulus,
2.More resistive to chemical aggressive environment than E-glass mesh.
3.Lower cost and better mechanical properties than for mesh made of special glassfiber.
4.The melting point of basalt fibers is 1450°C.
5.Lower elongation before brake than for synthetic material.
6.Easily milled using typical milling equipment. Does not stretch and pull as polymer meshes.
7.No special equipment is required to install the reinforcement.
8.Basalt mesh is environment friendly and based on naturally occurring material that is found worldwide


Basalt Rock Fibre Manufacturing
Technique:

Basalt Rock As Raw Material:
Technical Properties:
Chemical composition basalt rock:
Region of Basalt Rock in India:
Plant layout:
Manufacturing Process of Continuous Basalt Fibre (CBF):
Process Description:
The Main Characteristics of the Plant



Technical Properties:

High tensile strength,
quite durable,
Alkali & acids resistant,
High thermal conductivity.
Completely inert with no environmental risks.



Region of Basalt Rock in India:

Basalt rock (Decan Trap) an area of about 500,000 square KM cover large part of the Maharashtra,
Kutch,
Saurashtra,
Gujarat,
Decan,
Central India,
Madhya Pradesh,
Hyderabad region etc.



Conclusion:

Basalt Rock fibres have no toxic reaction with air or water, are non-combustible and explosion proof. When in contact with other chemicals they produce no chemical reactions that may damage health or the environment. Basalt base composites can replace steel and known reinforced plastics (1 kg of basalt reinforces equals 9.6 kg of steel). Basalt can replace almost all applications of asbestos and has three times its heat insulating properties.
Basalt is well known as a rock found in virtually every country round the world. Basalt rock is more in India (specially in Maharashtra). The cost of basalt is 10 times lower than that of raw materials for fibreglass. Basalt is more available than any other raw material. Also the melting temperature is lower, thus energy consumption lower. Thus, the cost of basalt fibre is considerable lower than that of similar materials. More workers are not required to operate the manufacturing plant.
Thus, I conclude that we can install the First project in India (Maharashtra).
