Which grade of concrete is used in pre-tensioned prestressed concrete structure?
42 mpa for pre tension and 35 mpa for post tensioned
What is difference between pre tension and post tension precast girders of bridge?
A simple explanation: PRE tensioned- cables are tensioned, and the concrete is cast around it. The tensioning is done BEFORE casting the concrete (PRE = before). POST tensioned- cables are placed inside of ducts or are greased to prevent bonding to the concrete, the concrete is cast around the cables, and then the cables are tensioned after the concrete has reached a desired strength. The tensioning is done AFTER the concrete is cast (POST = after).
Difference between pre-tensioned and post-tensioned?
what a wicked page, really helpfull Difference between pre-tensioned and post-tensioned?
Pre stressed concrete compared to Post tensioned concrete?
Prestressed concete made using high tensile wires which is stressed (as per the design load) before concreting, and post tensioned concrete made of Strands covered with duct, in this, wires/strnads are stressed after concreting then the ducts are grouted using cement slurry..
What is the definition of pre tensioned concrete?
Prestressed or pretension concrete uses wires and reinforcement to strengthen concrete's inherent weakness. It prevents cracking and buckling and adds years of useful life to the building structure.

What are the advantages and disadvantages between post tensioned slab and pre tensioned slab?
post tension: the forces considered as outer force since pre tension forces are internal forces.

What is the method of increasing the strength of a beam or rod by applying tension called?
Pre tensioned concrete best illustrates this concept. Tension in the rods becomes compression in the concrete once the cables are cut at the ends of the beam.
What is the definition of concrete nails?
Nails that are hardened for use in concrete
What is the definition of concrete images?
The definition of a concrete images is an image that cannot be disproved. This image can be proof of evidence for example.
What are the definition of bollard?
A bollard is a short, vertical post, usually made of wood, steel or concrete. The are used for mooring ships as well as traffic protection devices.
