What is post stress concrete?

Post-stressed concrete, or prestressed concrete, is a construction technique that involves reinforcing concrete with high-strength steel tendons before it is subjected to service loads. This process creates internal stresses that counteract external loads, enhancing the material's performance and allowing for longer spans and reduced structural elements. The tendons can be tensioned either before (pre-tensioning) or after (post-tensioning) the concrete is poured, providing flexibility in design and construction. This method improves durability, reduces cracking, and increases load-bearing capacity.
