Post-tensioning is a form of prestressing. Prestressing simply means that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed.

Impact of environmental stress on seagrass: For example, pharmaceuticals such as ibuprofen entering the marine environment may have an impact on seagrass. Studies have shown that high concentrations of ibuprofen can cause increased oxidative stress in seagrass, affecting its photosynthesis and metabolite production, thereby affecting its ability to adapt to other environmental stressors.

Sustainability: Post-tensioning technology is consistent with green building practices that emphasize material efficiency, reduced energy consumption and lower overall environmental impact. Post-tensioned structures contribute to more sustainable building projects by optimizing material use and reducing energy requirements
