Reinventing Concrete

Posted on May 06,2015 by AlexWilson in concrete

I’ve been in the San Francisco Bay Area for the past week speaking at various conferences. (When I travel I try to combine activities to assuage my guilt at burning all the fuel and emitting all that carbon dioxide to get there. Between conferences, I’m now spending time with my daughter in Petaluma and Napa.)

In my role with Environmental Building News and our GreenSpec Product Database, I get plenty of opportunities to research and write about innovative building products. That’s one of the really fun aspects of my job.

Use fly ash in concrete

Posted on May 06,2015 by Peterbilt in Kitchen or bath addition

**Fly ash can replace some of the Portland cement in a concrete mix** Manufacturing Portland cement uses a lot of energy and produces about 6% of the world’s carbon dioxide emissions. Replacing the 12% Portland cement mix in concrete with 15% to 25% Type C or Type F fly ash are fairly common, and mixes up to 60% are sometimes used. Contact your local Department of Transportation for advice about mixtures they've tested; this will help when talking to your building inspector and concrete contractor.
