Italy has developed a cement city that can purify the air!

   Who points out that air pollution has become the world's largest environmental killer. People exposed to dirty air are more likely to die over the next few decades than those living in cleaner places, according to a long-term who study.

   In response to the problem of air pollution, the Italian Cement Group has developed a new biodynamic cement that cleans the air around buildings. Manufactured from recycled waste marble and leftover aggregates, this cement is given a "biological" function by the combined photocatalytic properties of the Italian Cement's patented TX activity solution.

   The cement produces a chemical reaction through a titanium catalyst activated by ultraviolet light, which can absorb pollutants such as nitrogen oxides and sulfur in the air and convert them into inert salts, which can be washed off the walls when it rains. The cost of this biodynamic cement is not high, and its construction cost is only 4% to 5% higher than that of ordinary cement.

   The advantage of biodynamic cement is that it can withstand more pressure than standard cement, but it is also more flexible, helping architects to design exquisite building shapes and ensure surface quality.

   Secondly, the bright white cement panel of biodynamic cement is extremely active, which can use sunlight to activate titanium dioxide particles and absorb pollutants such as nitrogen dioxide in the surrounding air, so that the shape of the building is not easy to become dirty, so it appears brighter.

   In addition, solar panels capable of generating 140 kilowatts are installed on the glass roof of the pavilion, which consumes 40% less energy than traditional buildings.

   If the surface of a city like Milan is covered with about 15% of biodynamic cement, air pollution can be reduced by half. Dutch scientists have applied this material to roads, which can reduce pollution by 45%.

   Delhi, India, is the most polluted city in the world, with about 10,000 premature deaths due to air pollution every day, mostly from stroke, heart disease and cancer. What is more frightening is that the death toll is increasing rapidly.

   If this material can be widely used in the construction of cities with serious air pollution, the air pollution problem in these places will be well improved, and people's quality of life and health level will also be greatly improved.
