Health monitoring of prestressing tendons in post-tensioned concrete structures

Currently 90% of bridges built in California are post-tensioned box-girder. In such structures the steel tendons are the main load-carrying components. The loss of prestress, as well as the presence of defects or the tendon breakage, can be astrophic for the entire structure. Unfortunately, today there is no well-established method for the monitoring of prestressing (PS) tendons that can

Grouting of Pre/Post Tensioned Cable Ducts - The Constructor

Grouting of the post-tensioned cables in the post or prestressed concrete is carried out to provide permanent protection to the steel cables against corrosion. It also develops a bond between cables and surrounding concrete which fills the duct space and prevents water collection and freezing. Fig 1: Grouting Vent and Nosel.

16 Different Types of Concrete - Home Stratosphere

This concrete is commonly used in the construction of bridges, columns, ceilings and other structures that need to be strong. Pre-stressed Concrete Pre-stressed concrete is a special type of concrete that goes through the process of pre-stressing to achieve the required shape.

Precast concrete - Designing Buildings

Precast concrete - Designing Buildings - Share your construction industry knowledge. Precast concrete is a form of concrete that is prepared, cast and cured off-site, usually in a controlled factory environment, using reusable moulds. Precast concrete elements can be joined to other elements to form a complete structure. It is typically used for structural components such as; wall panels

Precast Concrete Structures

Precast portal frames with flat (or shallow inclination) roof structures comprising prestressed or reinforced beams of 6–8 m span supporting long-span precast folded plate roof elements, spanning around 20 m. This is a popular option for industrial buildings, and in the case of Figure 3.10 used in laboratory buildings.
