Australian Engineers Create Eco-Friendly Building Material
Imagine building houses with a new recipe that's good for the planet!
Australian engineers have invented a building material made from things like cardboard, dirt, and water.
This new material is much better for the environment because it creates only about one-quarter of the pollution that regular concrete does.
Plus, it's cheaper!
The special mix, which uses the ground’s natural soil, is also good at keeping houses cool in hot weather.
They hope to use this material in places with lots of cardboard waste and red soil, and even combine it with other materials like carbon fiber to make strong buildings.
Engineers developed a new building material made from cardboard, soil, and water.
The material has about one-quarter of the carbon footprint of concrete.
It eliminates the need for cement, and it's more cost-effective than concrete.
The method involves compacting a soil-and-water mixture inside cardboard formwork.
Rammed earth buildings naturally regulate indoor temperatures and humidity.
