1. COMPOSITION AND PRESENTATION
The BFRP composite rebar is made from high strength basalt fibers along with an extremely durable vinyl ester resin. The basalt fibers impart strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. BFRP rebar significantly improves the longevity of civil engineering structures where corrosion is a major factor. As compared to conventional steel rebars, composite rebars should be a suitable alternative to steel reinforcing in:
· Architectural Concrete: cast stone, architectural cladding, balusters, column facades, window
lentils, architectural precast elements, hand railing, and statuary and fountains, etc.
· Concrete exposed to deicing salts in: bridge decks, railroad grade crossings, median barriers
parking garage elements, and salt storage facilities, etc.
· Concrete exposed to marine salts in: seawalls, water breaks, buildings & structures near waterfront,
aquaculture operations, and floating marine docks, etc.
· Applications Subjected to Other Corrosive Agents:Wastewater treatment plants; petrochemical
plants; pulp/paper mills; liquid gas plants; pipelines / tanks for fossil fuel; cooling towers; chimneys;
mining operations of various types; nuclear power and dump plants.
· Applications Requiring Low Electric Conductivity or Electromagnetic Neutrality: Aluminum
and copper smelting plants; manholes for electrical and telephone communication equipment; bases
for transmission / telecommunication towers; airport control towers; magnetic resonance imaging in
hospitals; railroad crossing sites, and specialized military structures.
· Tunneling / Boring Applications Requiring Reinforcement of Temporary Concrete Structures:
Structures including mining walls; underground rapid transit structures and underground vertical shafts.
· Weight Sensitive Structures: Concrete construction in areas of poor load bearing soil conditions, remote
geographical locations, sensitive environmental areas, or active seismic sites posing special issues that the use of
lightweight reinforcement will solve.
· Thermally Sensitive Applications: Apartment patio decks; thermally insulated concrete housing and basements;
thermally heated floors and conditioning rooms.
2. PROPERTIES & APPLICATION
Reasons Why Composite R-bar is Superior to Epoxy Coated Steel Bar:
Non-corrosive
Tensile strength is more than twice that of steel
Non-metallic and non-conductive
Consistent modulus of elasticity
Deformation patterns are the same as with steel
Four times lighter than steel
Pre-fabricated ACI standard angles and bends available
Coefficient of thermal expansion more similar to concrete than that of steel
