We recently applied a low carbon concrete flooring system in a snack food company in the Philippines. The industrial flooring system is made out of recycled fly ash and slag. Here’s a link: http://resourceefficiency.wordpress.com/2009/08/21/low-carbon-industrial-flooring-site-visit/

Hi. My name is Rolan Duvvury and I am also an undergraduate research assistant for Dr. Doyoyo. As Derek said, we are currently researching the effects of heavy metals within the fly ash used to make CENOCELL. The main question is whether the fly ash is sequestrating these potentially toxic heavy metals. My friend Alex MacDougall, who is a fourth year Biology major is currently working on getting EPA approval for the material.

P.S. From my view, the final product is safe. It is just a solid block that replicates the look and feel of concrete. Its pretty interesting stuff to say the least. It emits no fumes and is hydrophobic. Unless you eat it, I really do not see any health effects for the final product. However, the process of making it can yield some toxic effects. As I said before, we are researching this.

Hey. I am currently part of doyoyo’s research team at Georgia Tech and am an undergraduate assistant. This is indeed fairly new research and will be quite revolutionary. Many markets such as China and India are exhausting their resources for producing cement concrete. This is unfortunate however Cenocell will provide a plethora of new concrete that is quite environmentally appealing. As for the health benefits, we have added a biology major to assist us in health tests to maintain standards with the EPA. I hope this clarifies some questions.

Hey Robin – That could be any number of things! Maybe you can contact your home inspector, and see what (s)he thinks could be happening? It could be anything from a chemical used in building to a gas leak. Please be safe!!

I have been living in a new construction home for 16 months. I have been smelling heated chemical vapors and think it is possibly coming from the concrete slab floors or the walls. I have tightness in my chest, have trouble breathing, burning in my chest, dizziness, confusion, heart palpitations, etc. So have my neighbors. What testing should I have done on my home? What chemicals do you think it is?

It sounds like this is pretty new technology, so these questions are probably still being researched. The issue of safety occurred to me, too…if the components are hazardous waste, how do they ensure that the final product is safe?

Very interesting. Here in the Philippines I just want to know; can we save money to build a house? How much?

Can we use volcanic ash?

This appears to be a very advantageous development. What I don’t see here is an analysis that demonstrates the product is safe for those who live or work in an environment that is using this product. What happens over long periods of time?
