How is voided slab system applied?

Voided slabs are constructed biaxially through the use of cube shaped disposable formworks made of recycled PP that are placed between lower and upper steel reinforcement. Casting of concrete is always in-situ.

The products are placed at the intervals specified in the project and connected to the lower reinforcement. After the upper reinforcement is placed, concrete pouring begins. The most important point to be considered while pouring concrete is to pour the concrete in two phases so that the products do not float, but not to allow the formation of cold joints between the two castings. In the first casting, the concrete is poured until it completely covers the edges of the disposable formworks. According to the class of the concrete and the weather conditions, when the concrete is slightly plasticized the second casting is carried out and the flooring production is terminated. Vibrator should be used at every stage of concrete casting.
