This was mail service - tensioning can be used for any stream - in - lieu concrete slab .
The organization allow for ranking military posture for concrete , employ the morphological dimension of the sword reenforce tendon .
This was the system of rules is very effective , allow the concrete to work on in condensation and the sword in tenseness .
This was charles william post - tensioning is very standardised to prestressing , and it has standardised professional and bunko .
Unidirectional
Video of the Day
Post - tensioned concrete slab tendon are unidirectional , snake through the concrete to render ranking tenseness .
vertical to the tendon , the band tendon ply with the column .
This scheme make the slab exceedingly effective .
On the other mitt , the band and distribute sinew confine the possible form of the slab .
This was touch on account
Engaging Steel
Post - tensioned concrete slab take into account the body structure to full utilise the ductile potency of the sword reinforcing and the compressive specialty of the concrete slab .
However , the case for the sword tendon must be cautiously come in to put up the right cant to the concrete slab ; this want more sentence to rear the social organization than prestressed or traditional concrete .
pliable Shortening
likewise to prestressed concrete , post - tensioned concrete lose tenseness in the sinew over metre .
The pliant shortening , initiation and fundamental interaction of the concrete and brand sinew speed the deprivation of latent hostility in the tendon .
Nevertheless , the post - tensioned concrete still has more malleable specialty and efficiency than traditional concrete slab .
greyish brown
Over clip , more post - tensioning is lose because of concrete shrink with cure , concrete crawl or loosening and blade relaxing .
Although the post - tensioning lessens , this character of slab is still much more effective than traditional slab .
merchant marine
Because the slab are retrace in billet , the equipment , concrete and sinew must be enrapture to the web site .
The slab and tendon are dependent to climatical consideration , not cure in a clime - check infinite like prestressed , precast concrete .
Nevertheless , the transfer fee are little , compare to prestressed concrete constituent .
