The article has an important point. The production and transportation of concrete is immensely energy-inefficient, due to the very-high temperature required to produce its components, including CEMENT, plus the fuel-intensive mode of transporting it (by cement mixer truck) to the job site. THAT is why concrete is not "green." By better understanding the nature of cement, it may be possible to make it stronger, lighter in weight, and for less energy...you idiot. To: ms.

This had to be ground in mills with additives to produce cement. How will this atomic structure work alleviate the energy consumption and gas emission to the atmosphere??

The writer gave absolutly no data or examples- Who even knew cement was an issue? Why is cement not "green"? This must be the most vague article on yahoo! Fire this idiot!
