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).
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..
Difference between pre-tensioned and post-tensioned?
what a wicked page, really helpfull Difference between pre-tensioned and post-tensioned?
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.
When are the tendons laid on the formwork for concrete?
Tendons are typically laid on the formwork for concrete after the formwork has been set up and before the concrete is poured. This process occurs during the preparation phase of post-tensioned concrete construction, ensuring that the tendons are properly positioned and secured to achieve the desired structural performance. Once the tendons are in place, the concrete is then cast around them, allowing for tensioning to occur after the concrete has cured.
How can I replace a mailbox post in concrete?
To replace a mailbox post in concrete, follow these steps: Dig out the old post and concrete base. Install a new post in the hole, making sure it is level. Mix and pour new concrete around the post, ensuring it is secure. Allow the concrete to dry and set before attaching the mailbox.
How do I install a mailbox post with concrete?
To install a mailbox post with concrete, follow these steps: Dig a hole at least 2 feet deep and wide enough to fit the post. Place the post in the hole and ensure it is level. Mix concrete according to the instructions on the bag. Pour the concrete into the hole around the post. Use a level to make sure the post is straight. Allow the concrete to set and cure according to the instructions on the bag. Attach the mailbox to the post once the concrete is fully cured.
