Members pre-stressed before the application of the superimposed loads and having all cables or
tendons fully bonded to the concrete or grouted within ducts.
Category 1
As Category 1, but having the tendons left ungrouted. This type of construction can sometimes be
recognized from the access points which may have been provided for inspection of the cables and
anchors. More
recently, unbonded tendons have been used in the construction of beams, slabs, and other member;
these tendons are protected by grease and surrounded by plastic sheathing, instead of the usual metal
duct.
Category 2
Members that are pre-stressed progressively as the building construction proceeds and the dead load
increases, using bonded tendons, as Category 1.
Category 3
As Category 3, but using unbonded tendons, as Category 2.
Category 4
