Advanced Construction Techniques for Precast Panel System
hhhhhhhhhhh
Implementation of advanced construction techniques using cellular concrete technology. One example of areas to which High Performance Cellular Concrete can be applied is in the development of a lightweight binary density insulating concrete panel system. This product could be a consideration for future applications in a new generation of buildings. These elements can be used for the construction in all types of building or structures worldwide. For instance affordable housing, schools, senior citizen’s centers, industrial, military and municipal facilities, and structures requiring service life in severe or hostile environments. Another precast application would be for new or replacing metal sheeting on the exterior skins on metal buildings.

These two illustrated samples represent this binary process. The thinner 7.62mm [3/8”] coloured finish would contain a density in the range of 1522 kg/m³ to 1762 kg/m³ [95 lb/ft³ to 110 lb/ft³]. And the second density following the first would be a 1041 kg/m³ [65lb/ft³] thermal density. Two main advantages with system is [1] Savings on colouring, since it only is encapsulated in this thin area, and not throughout the entire mix. [2] Thermal conductivity through both members lowering costs to heat or cool inside the structure. The binary system reduces the weight of the material in addition decreasing structural weight yet maintaining medium or high Mpa [psi].
Thermal conductivity [k] is defined as the rate at which heat passes through a material of unit area and thickness when there is a unit temperature change between the two faces of the material. The higher the [k] value of a material, the inferiour its insulation qualities.
