Voided Concrete = Lower Carbon Footprint:

From the desk of Alex Vondeling.

I’ve heard of voided concrete, but not yet used in any project.  This product by Cobiax USA Inc seems like a pretty intriguing green option.  I would assume it would not cost more and perhaps less than conventional structural concrete systems.  I checked with CVM (structural engineers).  While they  are familiar with voided concrete they have not used it in any of their projects – perhaps since steel and wood seem to be far more common structural materials.
