Memory steel is a new building material that can be used to reinforce both new and existing concrete structures. When the material is heated, prestressing is automatically triggered. This material can help avoid the difficult maneuvering involved in hydraulic prestressing.
In the future, memory steel could also be a proven method for manufacturing precast concrete parts with a previously unknown geometry. The hydraulic prestressing used to date creates friction in curved structures, which greatly limits the use of this method.
