Fly Ash health concern
I came across some articles regarding fly ash health concerns:
With little kids in a tight house and organic garden in the backyard, I’d rather not use fly ash in concrete even though there is no clear evidence that it actually poses health risk (yet). Since there are toxic materials in fly ash, I don’t want any potential toxic dust in the air/water now or at the end of its life cycle. I think more research is needed and I just don’t want to use it now.
When I told my contractor NOT to use fly ash, he asked me – what else would you like me to use instead? Is there an issue to tell him to only use Portland cement?
P.S. I know Portland Cement uses a lot of energy to reproduce. We have been doing our best to minimize our energy consumptions for many years and will continue to do that.
