Comparative overview
Glass fiber — Alkali-resistant glass
Strengths: High-zirconia chemistry improves survival in alkaline cementitious environments where ordinary E-glass degrades.
When to use: Select for GRC, concrete reinforcement, façade panels and mortar/cement systems.
Key tradeoffs: Specialized rather than maximum-strength reinforcement; heavier than polymer fibers and not a substitute for S-glass in high-performance structures.
Qualitative ratings (1–10 scale)
| Relative cost | 3/10 — Low — slightly above commodity E-glass because zirconia chemistry targets alkali durability. |
|---|---|
| EM transparency | 8/10 — Very good — electrically insulating and generally dielectric. |
| Temperature / fire resistance | 7/10 — Very good — non-combustible mineral fiber, but softening/strength retention is below silica, quartz and ceramics. |
| Impact / penetration resistance | 5/10 — Moderate — moderate energy absorption; chemistry is optimized for alkali resistance rather than maximum tensile/impact performance. Stored TDS elongation: 2%. |
| Electrical / thermal conductivity | 1/10 — Very low — electrical insulator with low thermal conductivity. |
| Specific tensile strength | 2/10 — 2/10 | 535.7 kN·m/kg | Product TDS |
| Atmospheric durability | 9/10 — Excellent — zirconia-containing AR glass is formulated to resist alkaline environments; sizing and sustained stress still influence ageing. |
| Sustainability (CO₂e) | 9/10 — 1.44 kg CO₂e/kg fiber — Low emissions — data quality: High |
