different strength and material characteristics than normal concrete. Many of the standard methods of design for concrete should be used with caution and only with full understanding of the physical properties of the material. It thus requires some level of specialized experience to produce competent, safe structural designs.

There are several different mix design formulas that can be used for , depending on the strength, or weight required as well as sound proofing and thermic characteristics

The compressive strength varies from about f’c 15 kg/cm2 (2500 PSI) on the low end of the spectrum at 669 lbs./yd3 (400 kg/m3) to 175 kg/cm2 (2500 PSI) on the high density end of the spectrum at (95 lbs./ft). Each mix design has specific thermal, insulation, sound and other intrinsic properties. These mixes can be used and integrated intro various types of construction to maximize the benefits and minimize the cost.

Because of its monolithic nature of the final building product, has a basic structural advantage over many other building systems that rely on piecemeal of multiple assembly element. The building loads and forces are uniformly distributed throughout the structural support system to the foundation, reducing stree concentrations under high load points, providing economy in construction, and more importantly, adding redundancy to the structural suport systems (a very important characteristic in high wind and seismic areas

Also, since overall gravity weights are reduced versus regular concrete construction, foundation systems costs can be reduced, sometimes significantly. Overall weight reductions also are of great benefit in high seismic zones, where the magnitude of earthquake loading is directly is related to the weight of the building. For high wind and seismic regions, lateral loads can be successfully resisted through careful engineering design and connection detailing consistent with conventional concrete construction.

Lab trials have proven that concrete, and other polistyrene concretes do not perform as well a normal concrete in the "pull out" test for reinforcement steel bars.

We do not recommend the use of concrete in structural elements without a professional structural analysis.
