Breatheable Concrete That Destroys Pollutants

There is some experimentation going on with this concrete that should have been done sooner. But, hey!

Photocatalytic concrete is an emerging green technology which incorporates titanium dioxide particles into Portland cement used to make concrete. Studies have shown that photocatalytic concrete can significantly reduce air pollution and keep concrete surfaces clean. When activated by ultra-violet rays from sunlight, titanium dioxide acts as a catalyst to accelerate the oxidation process that converts nitrogen oxides and other smog components such as fine particulate material, carbon monoxide and sulphur dioxide, to less harmful compounds. Photocatalytic concrete has the potential to significantly reduce smog-forming air pollutants in its vicinity, thus acquiring the moniker “smog-eating concrete”. the photocatalytic cement a perfect paving material as it successfully reduces the amount of toxins expelled by vehicles and inhaled by pedestrians. Italy and other areas of Europe have already paved many of their roads with the revolutionary material, but Chicago is reportedly the first city in America to adopt it, laying down a thin, permeable pavement for the bicycle and parking lanes on Blue Island Avenue and Cermak Road.

The cement is marketed under the trade names TX Active (Essroc, East) and TioCem (Lehigh Hanson, West).

Eindhoven University of Technology scientists have installed air-purifying cement onto a city block in Hengelo, Netherlands, and published the results, which found that it reduced nitrogen oxide air pollution up to 45 percent in ideal weather conditions.

I also understand that there are fellow humans that are testing it on their homes and found it to be quite effective in reflecting the sun. Which could help in reducing the electricity bill when applied.

Forced Green also wrote about smog eating tiles that are available.

So you can either lay a thin layer of concrete around your house for all of the benefits mentioned above or tile your roof for the same effect. All you have to do is just figure out what is the cheapest way to do it that is within your budget.

So what are you waiting for?

    My first thought was what is titanium dioxide? According to Wiki it’s also used as a food coloring 🙂

    I would like to see green concrete everywhere. And I mean the color green.

  3. Linda Says:

    HI Don …. I like the expansion of the green concrete but I think the green cement would be a little much everywhere. I know that green is calming but it might mess with someone’s depth perception in certain light.

  4. Chris Says:

    I love green concrete. it saves our life

    If Photocatalytic concrete has the potential to significantly reduce smog-forming air pollutants in its vicinity, why don’t we try to use it? It is so useful.
