Pre-stressed concrete is like rebar-enforced concrete, but with the added power of tension baked in. By adding stress to the concrete before it goes into service, deflection will be reduced or ...

Prestressing reinforcement doesn't necessarily make concrete stronger. But, it does increase the serviceability of concrete members by reducing the amount of deflection under load. This video explains ...

and then tensioned by twisting the threads at one end. Similar to building with prestressed concrete, this method allows for stronger parts, longer spans, less building material, and lighter ...

Notice how the top notch squeezes together in compression, while the bottom notch spreads apart under tension. Pre-stressed concrete is an ideal material for beam bridge construction; the concrete ...

During the 2025 World of Concrete trade show, the Post-Tensioning Institute (PTI) teamed up with the American Concrete Institute to put together an updated set of post-tensioned structural ...
