Most structural engineers and architects are
aware of the advantages of post-tensioned
concrete, which include the ability to use
thinner members, longer spans, lower deflections,
and lower prices. These advantages are well
known, but did you know that when compared to
other methods of construction, post-tensioned
concrete provides a more sustainable design
solution? This article examines six "unexpected"
advantages of post-tensioning in building
construction.

Unexpected Benefits Of Choosing Post-Tensioning
In Building Projects

• cost-savings
• construction with quickness
• less steel is used
• formwork and reshoring for the slab can be
  removed earlier
• follow-on trades can begin early
• sag and vibration on the floor have been reduced
• space and form flexibility in architecture
• building foundations with strength and flexibility

Cost-Saving
When compared to traditional reinforced concrete
construction, most of us are aware that
post-tensioning saves money in terms of concrete
and reinforcing steel quantities. The cascading
cost savings that occur in several components of
the total building cost may surprise people.
5
Construction With Quickness
Another advantage of post-tensioning is that it
allows for faster construction. Construction of a
floor can be done faster due to the reduced
materials utilised and the simplicity of the
formwork
6
Less Steel Is Used
Placing steel is one of the most time-consuming
aspects of construction, and because PT designs
lower the amount of steel required, slabs will be
ready to pour sooner. Unlike traditional concrete
slabs, which require about 5 to 7 lb./ft2 of
steel, post-tensioned flat slabs only require 2
to 3 lb./ft2.
7
Formwork And Reshoring For The Slab Can Be
Removed Earlier
Once the concrete reaches a strength of 3000 psi,
PT slabs are ready to be stressed. Stressing the
tendons 2 to 3 days after the pour is extremely
common. After the stressing is finished, the
formwork can be stripped and transported to the
next pour.
8
Sag And Vibration On The Floor Have Been Reduced
Increased occurrences of vibration and deflection
can be caused by the construction of lighter and
longer floor constructions. However,
post-tensioning the concrete results in two
crucial properties that considerably reduce
vibration and sag. For starters, the wires'
profile within the concrete creates a load
balancing effect.
9
Space And Form Flexibility In Architecture
To preserve their strength and serviceability,
traditional concrete slabs must be a certain
thickness. Post-tensioned concrete, on the other
hand, allows you to produce thinner and longer
slabs without sacrificing structural
serviceability and strength.
10
Building Foundations With Strength And Flexibility
Mat foundations can benefit from post-tensioning,
which has a number of advantages. The cost of the
foundation system will be reduced when the depth
of the foundation system is reduced. Source
