Concrete is the most commonly used building material in the world. And now, by adding the invisible wonder material graphene to it, researchers have taken a step towards a more sustainable construction industry. The new graphene-laced concrete is two times as strong and four times as water-resistant as the standard stuff, shows a new study…
