>Yes its real. The concrete paving stones were shown to reduce nitrogen oxides by 25% to 45%, by converting it into nitrates. The concrete also breaks down algae and dirt, and uses titanium dioxide that reacts with sunlight, to produce its effects. The Eindhoven University of Technology confirmed these results last fall when they tested it on a busy road in Hengelo, an area of the Netherlands. It is made by Struyk Verwo Infra and is already available for purchase.
The concrete can be mixed with asphalt for use on roads, or used for self-cleaning and air-purifying building walls. While the concrete stones cost 50% more than regular concrete, road building costs are only 10% higher. The building material of the future, self-cleaning and detoxifying concrete. It almost sounds like science fiction.
