better distributing the stresses inside the construction to make exceptional use with the reinforcement. By way of example, a horizontal beam tends to sag. Prestressed reinforcement along the bottom of the beam counteracts this.

Polymer concretes are often employed for the restore and development of other purposes, for example drains.

Bonded tendons include bundled strands placed inside ducts Found within the bordering concrete. To be certain complete protection into the bundled strands, the ducts have to be force-stuffed with a corrosion-inhibiting grout, without the need of leaving any voids, next strand tensioning.
