Pre-stressing and Post-tensioning
When combined with a proprietary factory applied anchorage, the Aslan 200 bars can be used as pre-stressing or un-bonded post tension tendons or earth anchors. Occasionally, the Aslan 200 bars are used as traditional concrete reinforcing bars, typically in restoration or repair situations.
Since 1993, Hughes Brothers has been at the forefront of worldwide academic and industry efforts to define consensus FRP standards and methods. Hundreds of structures have extended service lives due to Aslan 200 Carbon Fiber Reinforced Polymer (CFRP).
Aslan™ 200 bars and tendons are typically used to strengthening existing structural members (concrete, wood, stone or masonry) in flexure and shear. Structures that are deficient due to either a structural flaw, deterioration or because of a change in use can often be brought to a useful capacity using Aslan 200 series Carbon Fiber Reinforced Polymer (CFRP).
Due to their extremely high strength and stiffness, along with the fact that they will not rust or corrode and are very light weight, Aslan 200 bars are often added to the concrete cover of an existing structure using a technique called “Near Surface Mount” or NSM strengthening. The method is analogous to adding “band aid” rebar to the structure.
