Building materials will no longer be the same: the revolutionary invention for the houses of the future12 October 2021
We all know that concrete is the most widely used building material on the planet. Statistics show that, annually, about 3 tons of concrete per capita are consumed on the planet.
Although very popular, few people know that concrete has a significant negative impact on the environment, so engineers have discovered a revolutionary method to turn classic concrete into a more environmentally friendly material. , but to keep its properties.
Researchers say that only the concrete industry is responsible for about 8% of global carbon dioxide emissions. Concrete production also consumes about 10% of the world’s industrial water.
As we know, concrete is made of water, cement and fillers such as sand. Researchers at the National University of Singapore have shown that they can reduce the amount of sand needed to make concrete by replacing it with a concrete. light and light clay material, obtained from waste from excavation work on construction sites around Singapore.
The clay was heated to about 700 degrees Celsius to gain active properties to increase the bonding capacity of the concrete. The activated clay was then used to replace up to half of the powder. fine sand usually used in the manufacture of concrete. The result was a high-performance, extremely strong concrete that can reduce the amount of concrete needed in a construction project.
This project is a historic one, because it is the first time that used clay has been used successfully as a concrete filler.
The research group is also exploring the use of other waste materials to replace concrete filler and the use of seawater and sea sand to reduce dependence on freshwater imports. and river sand from Singapore.
At the same time, researchers are studying the use of concrete as a carbon capture material to reduce its carbon footprint and therefore make it less polluting.
