Alkaline Resistant Fiberglass (AR Fiberglass) is specially designed to resist corrosion in alkaline environments, primarily found in cement and concrete. It contains a high percentage of zirconia (ZrO₂), usually above 16%, which gives it excellent durability in cementitious applications.
Key Properties:
High alkali resistance (ideal for concrete)
High tensile strength
Lightweight and flexible
Non-corrosive and non-conductive
Long durability in harsh chemical environments
Common Uses of Alkaline Resistant Fiberglass:
1. GRC (Glassfiber Reinforced Concrete)
AR fiberglass is the standard reinforcement in GRC products like wall panels, decorative elements, and facade claddings.
2. Precast Concrete Products
Manhole covers, channels, curbstones, and railway sleepers are reinforced using AR fiberglass to improve structural performance.
3. Mortar and Plaster Reinforcement
Prevents surface cracking and improves mechanical properties of cement plasters, rendering, and repair mortars.
4. Waterproofing and Surface Coating
Used in membranes and coatings exposed to alkaline conditions, ensuring long-lasting performance.
5. Flooring Systems
Enhances load-bearing capacity and impact resistance of industrial and commercial concrete floors.
6. Rebar Alternative
AR fiberglass bars and mesh are used as a non-metallic alternative to steel rebar in corrosive environments like marine and sewage systems.
