Prestressed concrete is a construction technique that involves introducing internal forces into the concrete before it is subjected to external loads. These internal forces are typically in the form of pre-compression, which counteracts the tensile forces that the concrete would normally experience when subjected to loads. The process of prestressing involves placing high-strength steel tendons or cables, called prestressing tendons, into the concrete element before it hardens. These tendons are tensioned using hydraulic jacks, applying a significant amount of force to the concrete. Once the tendons are tensioned, they are anchored at the ends of the concrete element to maintain…
