Pre-Tensioning and Post-Tensioning in Prestressed Concrete

The prestressed concrete design of a structure is influenced by either of the two processes, pre-tensioning, and post-tensioning. Pre-tensioning can be further classified into two egories such as linear pre-tensioning and circular pre-tensioning.

Prestressed Concrete (Post Tensioning Concrete): Grouting

Grouting Pump for Post Tensioning. 1. Model: CNM-HB Series. 2. Motor Voltage: Three Phase, 380V, 50hz, or Single Phase, 220V, 50Hz. 3. Usage: For grouting cement (or concrete) to tunnel of ducts in post tensioning and prestressing construction. 4.

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.

Types and Causes of Concrete Deterioration

concrete, the passive corrosion rate is typically 0.1 µm per year. Without the passive film, the steel would corrode at rates at least 1,000 times higher (ACI 222 2001). Because of concrete’s inherent protection, reinforcing steel does not corrode in the majority of concrete elements and structures.

Post Tensioning Tendons, Ducts and - Concrete Construction

01.05.1973· Post Tensioning Tendons, Ducts and Grout Materials. There are two main reasons for grouting the ducts of post-tensioned concrete meers. One is to provide efficient bond between the prestressing steel and the concrete meer so as to control the spacing of cracks at heavy overload. This increases the ultimate strength of a structural meer.
