"...once humans arrive on the red planet, they will require high quality buildings in which to live and work...The first colonizers will quickly have to find a way to build structures using the planet’s own resources. But how?

The key material in a Martian construction boom will be sulphur, says the Northwestern team. The basic idea is to heat sulphur to about 240 °C so that it becomes liquid, mix it with Martian soil, which acts as an aggregate, and then let it cool. The sulphur solidifies, binding the aggregate and creating concrete. Voila—Martian concrete."
