What is post-tensioning in construction?
Post-tensioning systems highly effective construction technique that involves reinforcing concrete with high-strength steel bars or strands that are tensioned after the concrete has hardened. This process creates a stronger and more durable structure, making it widely used in bridges, parking structures, high-rise buildings, and other types of construction projects. In this article, we will explore what post-tensioning is and how it is used in the construction industry. How Does Post-Tensioning Work? Post-tensioning is typically done in two stages. The first stage involves placing the high-strength steel bars or strands, known as tendons, in ducts or sleeves within the concrete forms before pouring the concrete. Once the concrete has hardened, the tendons are tensioned using hydraulic jacks, which places the concrete under compression. This compression counteracts the tension forces that the structure will experience during its lifetime, resulting in a stronger and more durable cons
