What is the difference between pre tensioned and post tensioned concrete?
This is achieved by tensioning the steel tendons present in the structural members. The difference is that in pretensioned concrete, the tendons are tensioned prior to pouring of concrete while in post tensioned concrete, tendons are tensioned after putting of concrete.Click to see full answer.

Beside this, what is the difference between pretension and post tension concrete?In pre-tensioning the stressing wires or tendons are stressed prior to placing concrete as shown below. In post-tensioning the wires or tendons are stressed and each end is anchored to concrete section after has been cast and has attained sufficient strength to safely withstand the prestressing force, as shown below.Also Know, what is pre tensioning concrete? Pre-Tensioning in Prestressed Concrete Pre-tensioning is accomplished by stressing wires or strands, called tendons, to predetermined amount by stretching them between two anchorages prior to placing concrete as shown in fig. 1. The concrete is then placed and tendons become bonded to concrete throughout their length. Consequently, which is better pre tensioning and post tensioning? Post-tensioning There is relatively less loss of prestress due to concrete shrinkage as at the time of prestressing concerete has already been cured. Corrosion of steel is less as compared to pre-tensioning. There is more flexibility in design.What is a post tensioned slab?Post-tensioned (PT) slabs are typically flat slabs, band beam and slabs or ribbed slabs. PT slabs offer the thinnest slab type, as concrete is worked to its strengths, mostly being kept in compression. Longer spans can be achieved due to prestress, which can also be used to counteract deflections.
