In the search for alternatives to cool environments without increasing energy consumption, scientists from the Smart Cities Institute (ISC) of the Public University of Navarra have developed cement 2.0.
It is a deep white cement that reflects sunlight and manages to reduce the temperature of buildings without the need for additional energy.
“This project has been recognized with an international award, the Nanophotonics Research Award for Innovative Sustainability, awarded during the Metamaterials 2024 conference, held in Crete (Greece).”
With this new cement, it is possible to “improve the reflective properties of cement against solar radiation by controlling its porosity and adding small particles in microscopic and nanometric sizes.”
It can be said that cement 2.0 cools itself thanks to solutions that surpass the conventional offer in this sector.
In the composition of this product, which is extremely white to reflect sunlight, “special additives have been used so that the cement is able to emit the accumulated heat into the atmosphere.”
The institute’s next goal is to create an intelligent cement that would be based on “phase change materials,” with the ability to modify its properties depending on whether the ambient temperature is high or low.
