Why Scientists Are Excited About Using Soil As An Alternative to Brick In Construction

Scientists in the UK are developing a method to transform normal soil into a novel building material that could one day cut our dependence on traditional brick.

The problem with brick production is that it requires firing a kiln at extremely high temperatures, which is costly and creates pollution.

“For a fired brick, that is typically fired at over 1,000 degrees centigrade, and to make the ingredients you need for cement, you need to fire that at 1,450 degrees centigrade,” says Alastair March, a researcher cited in the video report.

To come up with an environmentally-friendly alternative, researchers at the University of Bath are experimenting with a technique called geo-polymerization.

By adding certain compounds to subsoil and curing at a temperature of only 80 degrees centigrade, they have found it possible to transform dirt into construction material.
