Merging

The introduction, "ecotower.jpg", "One Bryant Park constructio.jpg", and The Durst Organization link were merged from Bank of America Tower at One Bryant Park, which now redirects here. Jaxl 15:01, 14 July 2005 (UTC)[reply]

Naming

Shouldn't the article in some way reflect the other popular name for the building, One Bryant Park? Danlurie 02:39, 16 July 2007 (UTC)[reply]

concrete mix

"The construction of the Bank Of America tower was done by using concrete manufactured with the byproduct of blast furnaces. The mixture used in the tower concrete are 55% cement and 45% blast furnace slag. In fact the mixture of cement and slag cement makes the concrete stronger. Use of byproduct slag cement also causes less damage to the planet by reducing the carbon dioxide produced by normal cement manufacturing, where each ton of cement produced yields a ton of CO2 into the atmosphere."

Im curious why this is notable. Slag Concrete and Flyash Concrete are incredibly common. Hell, my research in concrete optimization for roads uses those two products. I also dont like the mixture being 55 percent cement and 45 percent slag. What this means is that we have a 100 percent paste concrete. No aggragrate???? thats amazingly expensive. also those statistics are meaningless if you dont know the water cement ration. I also dont like the statement of:

"where each ton of cement produced yields a ton of CO2 into the atmosphere."

Is this during the manufacturing of cement?? or during setting? Because if its during setting it makes no sense strickly on a mass balance scale. and if its during manufacturing is your stat taking into account the CO2 released during steel manufacturing(which is where a large portion of slag comes from)?
