Stronger concrete made using waste vegetables
Concrete manufacture is a major source of pollution. The production of Portland cement, a main ingredient in concrete, is estimated to be responsible for up to 8 percent of the total worldwide emission of carbon dioxide. At Springwise, we have recently covered several innovations aimed at reducing the carbon footprint of concrete production. Some of these have focused on using different methods to make Portland cement more sustainable by adding graphene. Now, engineers at Lancaster University, along with industrial partners at Cellucomp Ltd, have come up with another method. They have devised a way to strengthen concrete and make it more environmentally friendly by adding extracts from root vegetables.
