CCL Post-Tensioned Slab solutions represent continuous development through involvement in building structures worldwide. CCL present intelligent solutions to some of the common restrictions faced by architects, engineers and contractors.

To obtain maximum benefits of CCL’s post-tensioned Slabs, it is recommended for the system to be incorporated into the building structure at early design stages.

Due to significant benefits of CCL Tensioned Slabs for developers, architects, engineers, contractors and end-users, their use is growing in popularity worldwide. Post-tensioning technology has been used extensively in building construction since 1960’s and with the promotional effort from CCL international network millions of square meters of post-tensioned slabs have been built for use in buildings of various functions.

CCL post-tensioned slabs offer:

• Open-plan spaces with large spans not restricted by awkward columns
• Flat slabs without drop elements that restrict the layout of partitions and services
• Thin slabs that increase planned clearance under ceilings or reduce total building height
• Greater freedom in architectural shapes of slabs and positioning of columns
• Slabs with less or no expansion joints
• Slabs with reduced, simple to fix reinforcement and less concrete to pour
• Less formwork due to faster stripping and redeployment of formwork

Architectural Intelligence
CCL post-tensioned slabs can bring unique freedom over conventional building methods. It allows increased spans to be achieved reducing the need for columns within the structure through more efficient and stronger floor slab design. It also removes the need for drop elements allowing a clean simple floor for the layout of services. Complicated floor plans that were not achievable with conventional methods can now be realized through CCL post-tensioned slabs.

Commercial Opportunities
CCL post-tensioned slabs create thinner slabs making valuable extra ceiling height between floors available as extra floors. This can produce extra valuable rentable floor area within the same overall building height.

Strong Fundamentals
A CCL designed post-tensioned slab can contain less concrete (20% to 30%), minimal quantity of reinforcement and less complicated re-bar shaping. The slabs require less formwork due to faster stripping and redeployment of shuttering. All this makes CCL Post-Tensioned Slabs simpler and faster to build than conventional slabs.

Structural Reliability
CCL post-tensioned slabs show reduced cracking for improved durability and lower maintenance costs. Their deflection can be controlled by varying the amount of post-tensioning to balance any portion of applied loads immediately after stressing. CCL Post-tensioned Slabs are lighter than RC slabs resulting in reduced foundation size and reduced seismic actions. The compression in CCL Post-tensioned slabs allows larger distance between expansion joints.
