Railway and metro infrastructure faces vibration, dynamic loads, moisture, abrasion, and continuous operational stress. From platforms and depot floors to precast components and underground works, concrete must resist cracking and perform reliably over time.
Glassman AR Glass Fibres by DD Solutions help improve concrete durability by controlling micro-cracks, reducing permeability, improving surface integrity, and supporting long-term serviceability. For rail and metro projects, Glassman works best where crack control, clean finishing, and non-corrosive reinforcement are priorities.
Railways & Metros Projects?
Rail infrastructure does not get much rest. Concrete in these environments must perform under movement, vibration, moisture, and daily service loads.
Glassman AR Glass Fibres help improve the concrete matrix by reducing micro-crack development and supporting durability. This helps reduce surface deterioration and improves the service performance of non-primary structural concrete elements, platforms, floors, precast products, and repair sections.
Key Benefits
Typical Applications
- Metro station platforms
- Railway platform slabs
- Depot and maintenance yard floors
- Utility trenches
- Precast drainage channels
- Walkways and service slabs
- Underground concrete works
- Tunnel-related precast elements
Usage & Mixing Guildlines
- Add during final mixing stage
- Ensure uniform dispersion
- Use project-specific trial mixes for rail and metro specifications
- Confirm compatibility with concrete grade and admixtures
- Validate finishing quality for platform and floor applications
Quality Standards
- Project-specific specification review
- ASTM C1116/C1116M recognizes glass fibre-reinforced concrete as Type II fibre-reinforced concrete containing alkali-resistant glass fibres
Recommended Fibre Types
Glassman AR Glass Fibre – 12mm
Suitable for platforms, floors, walkways, precast units, and general concrete applications.
Glassman AR Glass Fibre – 16mm
Suitable for thicker slabs and enhanced crack-control applications, subject to technical approval.
Suggested Dosage
0.5 kg to 1.0 kg per m³ of concrete
Final dosage should depend on application, concrete grade, exposure condition, finishing requirement, and project specification.
Technical Note
Recommended dosage and fibre length should always be finalized based on the application, mix design, site conditions, and trial results.
For structural replacement of steel reinforcement, project-specific validation by a qualified engineer is required.
