Researchers at the University of Hidalgo in San Nicholas, Mexico, have created a new cement mixture that can be pedestrianized and the roads self-illuminate without any artificial energy. This cement mixture includes phosphorescent materials. Phosphorescent elements absorb sunlight during the day and then illuminate sidewalks and even car roads at night. According to the researchers, the special cement can even absorb enough sunlight on cloudy days and maintain up to 12 hours of lighting. Therefore, the use of phosphorescent materials can further reduce the dependence on fossil fuels.
The researchers said that by using additives, crystals that normally appear in cement production can be prevented. The amorphous structure allows light to pass through. In addition, by changing the ratio of additives, the cement produced has two luminous intensities and colors.
Although the researchers pointed out that special phosphorescent cement manufactures like ordinary cement, phosphorescent materials do not change the structure of the final product, but for reasons of cost, the luminescent cement can be coated on the surface of ordinary cement as a luminescent coating. The researchers pointed out that there are still some obstacles that need to be overcome before the phosphorescent cement is used in commercial applications. For example, the researchers are still studying how to repair the phosphorescent cement after it has been destroyed.
