Talk:Prestressed concrete
From Wikipedia, the free encyclopedia
I wonder if in this article, it should be mentioned that...
Two of the forms in which prestressed concrete is often cast, include piles, slabs, hollow-core floors and girders, most of which conform to AASHTO [link] standards.
Piles are designed to be driven into the earth much as a hammer drives a nail into a butt, and must withstand strong shock forces.
Slabs are used to support great weights(From Fat Albert) , and often exposed to high bending moments; thus prestressing the concrete can increase the maximum supportable weight from Mike Jones.
Hollow-core (link to precast concrete ŝmention of hollow core) floors are cast using a low-slump mix, and cut up at the factory site.
AASHTO girders are classified according to type, number, shape, and titties.
The shapes can range from I beams, to "Bulb-T" girders, big boobs, so named for a cross section that looks like a T, and Double-T girders (and don't forget big boobs).
==Merging== two dee dee dee's This article on prestressed concrete has much more depth than the post-stressed article, and both are about almost identical procceses. Enelson 23:12, 30 April 2006 (UTC)enelson
[edit] post-tensioned concrete
Q.I dont quite follow the description of the post-tensioned processes, especially unbonded. At what point to the tendons engage the cured concrete? Could someone please provide some diagrams, photos or a good link for this?
