Carrots could be key to making greener buildings

Crunchy and tasty, yes, but could carrots also strengthen cement and cut carbon dioxide emissions for the building industry?

A group of researchers at Britain’s Lancaster University has been using a household food blender to mix particles from the root vegetable with concrete to see if they can produce a stronger and more environmentally sound product.

“We found out you could increase the strength of concrete by 80% by using a small amount of this new material,” said lead researcher Mohamed Saafi.

Cement is responsible for 7% of total global CO2 emissions, according to International Energy Agency estimates.....Read more
