Micro Synthetic Fibre for Concrete Reinforcement
Micro Synthetic Fibre is a specially engineered secondary reinforcement used in concrete to control plastic shrinkage cracking and enhance durability at early stages. It improves the internal bonding of concrete, reduces permeability, and strengthens the surface integrity of rigid pavements and structural elements.
The product is recognized and accredited by leading authorities including BIS, CPWD, PWD, W&R, MES, Railways, Metro, AAI, CRRI, IRC and NHAI, and has been successfully implemented across multiple infrastructure projects in India.
Applications
Key Benefits in Rigid Concrete Pavements
Control of Plastic Shrinkage Cracks
Reduces early-age cracking caused by rapid moisture loss, improving surface durability and appearance.
Reduced Permeability
Minimizes water penetration and ingress of harmful chemicals, thereby improving long-term durability.
Improved Abrasion Resistance
Enhances resistance to surface wear, cavitation, and pitting under traffic movement.
Enhanced Bonding & Tensile Strength
Improves cohesion within the concrete matrix, increasing split tensile strength and overall performance.
Better Surface Finish
Reduces segregation and bleeding, resulting in uniform concrete quality.
Industry Acceptance & Field Performance
Micro Synthetic Fibre has been widely used in projects executed by State Government Departments and NHAI across India, delivering consistent performance over the years. Subsequent circulars and technical encouragement from MoRTH, NHAI, and DMRC further support the adoption of fibre-reinforced concrete technology in infrastructure development.
The Hon’ble Minister of Road Transport and Highways has also emphasized the importance of fibre reinforcement in road construction, reinforcing the Government’s focus on durable and sustainable infrastructure.
Our Commitment
With over two decades of experience in the road construction sector, backed by a dedicated in-house technical and marketing team, we ensure:
We remain committed to supporting India’s infrastructure growth with sincerity, trust, and integrity.
