(I meant smelt of course) A third possible advantage of air-cleaning concrete may be that it prevents corrosion of the building and thus increases its expected life-span. Smet?

There were so many fleas in my house they infested my front lawn and came back to haunt me after he left, every summer for three years. Please put a flea collar on your cat. Has anyone ever solar fired concrete? I'd imagine titanium-oxide would be too expensive to use as a building material, unless it provided structural strength advantages as well as filtered the buildings air. If it only filters the air that blows by the building and provides no strength, I can't see anyone ever coughing up the cash for it. Maybe its possible to convert these polluting oxides into harmless salts using a metal or mineral that is less expensive than titanium. Or is titanium onlly expensive because it takes a lot of energy to smet? (maybe we could solar fire titanium...) I once had an eco-nut roommate that refused to put a flea collar on his cat.

Mixing ordinary concrete for the application, I can do. Try a small porous batch ? will have to really think hard A material that needs extra care in preparation, application, and maintenance

Mixing ordinary concrete for the application, I can do.

It's a sure bet that we'll be in deep trouble if no one is trying to make a difference in these areas. It takes many projects like these to create successful products that can make a difference. This is how it's done, folks. To throw stones at that intent is just weird. Three cheers for these innovators!
