US media: China and the United States have developed cement that helps buildings cool down!
Scientists named this material "photonic structure cement".
August 20, CNN report from the US.
Chinese and American scientists have developed a building material that interacts with light and heat, helping buildings to cool down rather than accumulating heat inside like ordinary cement and concrete.
Using this material can reduce the indoor temperature of buildings by 5 degrees Celsius during high temperatures in the day.
When this cement solidifies, a special structure forms on its surface.
This structure is composed of analogs similar to natural calcium acetate crystals, which reflect visible light very well.
This allows us to reduce the indoor temperature of buildings by 5 degrees Celsius under conditions similar to hot days.
This material, called "photonic structure cement" by scientists, was developed by a team of material scientists from China and the United States under the leadership of Professor Miao Changwei from the East University (China).
This kind of building will remain cool instead of heating up when it's hot.
To demonstrate this, scientists made miniature house models built with both ordinary and "photonic structure cement" and observed their reactions to sunlight and heat energy.
These experiments showed that the internal temperature of buildings could be reduced by 5 degrees Celsius during the hottest part of the day.
Scientists concluded that this would significantly reduce the cooling costs of houses.
