Raised floor system

The study was aimed at evaluating the reliability of composite panels composed of sandstone slabs of different thickness reinforced with a glass wool layer, for interior and exterior raised floor.

Project goals

• Determination of the strength of composite panels composed of sandstone slabs reinforced with glass wool;
• Evaluation of the reliability of the reinforced panels for interior / exterior raised floor.

Innovative aspects

Design of specific laboratory tests to assess the strength of ornamental stone slabs reinforced with glass wool.

Performed activities

1. Analysis of the reference standards for raised floor characterization;
2. Design of specific laboratory tests to assess the strength of ornamental stone slabs reinforced with glass wool for raised floor;
3. Determination of the pedestal load bearing capacity with varying the screwing degree of the threads;
4. Determination of the concentrated load strength of the reinforced sandstone slabs with different thickness and size;
5. Determination of the strength of the reinforced sandstone slabs to freezing cycles (UNI EN 12371, Figure 3) and thermal shock (UNI EN 14066);
6. Interpretation of the results of the mechanical characterization;
7. Proposal for amendment of the raised floor system components.
