Basalt Fiber Reinforced Concrete (BFRC) is a type of concrete that incorporates basalt fibers to enhance its mechanical properties. Basalt fibers are made from volcanic rock and offer high tensile strength, durability, and resistance to environmental impacts.
BFRC improves concrete's flexural strength, impact resistance, and fatigue strength, making it suitable for various construction applications.
Additionally, it provides better thermal stability and chemical resistance compared to traditional fibers like glass or steel reinforcement.
Here is a detailed explanation about Basalt Fibre Reinforced Concrete
Properties of Basalt Fibres[edit | edit source]
- Basalt fibre is known for its high tensile strength, typically ranging from 2.8 to 3.1 GPa (Gigapascals).
- It has an elastic modulus of about 85-87 GPa, making it three times stronger than steel in specific strength.
- Basalt fibres are also lightweight, with a density of 2.67 g/cm³.
- They exhibit excellent chemical resistance, making them suitable for use in alkaline, acidic, and salt environments.
- Additionally, basalt fibres have a high temperature resistance, ranging from -269°C to +650°C.
Challenges of Basalt Fibre Reinforced Concrete[edit | edit source]
- BFRC has very low workability.
- Assuring even distribution of Basalt Fibres in concrete mix is also difficult.
- Basalt Fibre are costlier than Steel Reinforcement.
