In this episode, Seth interviews Neel Khosa from AMSYSCO, a post-tensioning supplier, to introduce post-tensioning and its history. Post-tensioning is a form of concrete reinforcement that uses high-strength steel cables inside concrete. It is about five times stronger than conventional rebar and is used in pre-stressed concrete. Unbonded post-tensioning is the standard for high-rise construction and large concrete structures in the US. The advantages of post-tensioning include material savings, reduced construction time, improved seismic behavior, and reduced deflections and vibrations. The future of post-tensioning includes its use in office buildings and the development of new systems.
