WebWhat is AS 3600 Design Principles: Post Tensioned slabs is the most commonly used solution for slabs all around Australia, especially for big developments, it is considered as the first option since it offers many benefits from bigger spans to less concrete and faster construction speed. It involves placing empty ducts and pushing strands ... Web1.2 Disadvantages of Post-Tensioned Flat slabs: 1. Corrosion: As there are a number of tendons and wires spread inside the post tension slab, it can result in corrosion. But, this tendency to corrode depends on the quality of the material used. 2.Complexity of work: Only skillful professional can manufacture post-tensioned slabs. The

Web6 Jan 2006 · A post-tensioned system will move 20% to 30% more than conventionally reinforced concrete. A good rule of thumb is that a post-tensioned system will move about 1 inch for every 100 feet of slab that is not restrained by a lateral system. If the edge of the slab is 50 feet away from the nearest shear wall, when post tensioned this edge will move ... WebUnbonded Post Tensioning .
