4 Main Data for Slab anchorage 

5 Application

The multistrand slab anchorage systems is normally adopted for bonded tendon.

The strands are individually gripped in one slab anchor head unit and tramsmits their prestressing forces by means of slab anchor plate casting unit.

The strands are stressed individually by means of a mono strand jack.

The strands are contained in one flat duct which is made of corrugated galvanized or non-galvanized metal.

To ensure corrosion protection and to give adequate bond strength, the tendons are filled with suitable cement grout mix after complete stressing of the strands.
