Composite rebar represents a compelling alternative to steel reinforcements with advantages including corrosion-resistance, improved durability, lightweighting, enhanced ease-of-installation, greater tensile strength and long service life.
Corrosion of steel is one of the main causes of failure of concrete structures, caused by concreate exposure to de-icing chlorides. Light weight composite rebar is impervious to corrosion, and a proven successful alternative that can be utilized for structures requiring additional strengthening and long service life.
Light-weight composite rebar can be utilized for bridge railings or traffic barrier systems to prevent corrosion from concreate exposed to de-icing chlorides and improve their design – matching different site needs.
Bridge approach slabs are part of concrete applications exposed to de-icing chlorides. Light-weight composite rebar can be utilized for structures requiring additional strengthening, following severe failure in flexure and levels of deterioration.
Light-weight composite rebar can be utilized for median barriers to prevent corrosion from concreate exposed to de-icing chlorides, improved strengthening and different shape options for bridge traffic.
Structures that become deficient due to a structural flaw, deterioration or change in use can often be brought to a useful capacity using Carbon Fiber Reinforced Polymer (CFRP) materials. Due to their high-strength/stiffness and anti-corrosiveness, CFRP materials can be used for repair and structural strengthening for “event" loading of masonry, restoration of cracked masonry, pre-stressed concrete bearing piles, reinforced concrete sheet piles, gravity walls and historic preservation.
Composite rebar acts as an electrical isolator and avoids stray and leakage currents in concrete exposed to high voltage and electromagnetic fields. This includes areas like: light & heavy rail, hospital MRI areas, high voltage substations, cable ducts & banks, aluminum smelters & steel mills, radio frequency sensitive areas and high speed highway tolling zones.
Composite reinforced concrete pavements are designed and constructed to provide durable and comfortable driving surfaces. Ideal for heavy-traffic highways and heavy load pavements like: salt storage facilities, continuously reinforced concrete paving, precast elements such as manhole covers, culverts, rail plinths and grade crossings.
