Dutch researchers investigate whether they can make cement out of steel slag

Steel production generates each year around 125 million tons of steel slag worldwide. This giant mountain of leftovers is largely considered a waste material. But according to the professor of building materials at the Dutch university of Eindhoven Jos Brouwers steel slag and cement have similar mineralogical composition, so he's undertaking a four-year research project to explore whether it’s possible to use slag as an alternative to cement.

The cement industry emits a very high amount of CO2: five percent of the global total. A cement substitute with no extra CO2 emissions would, therefore, be most welcome.
Brouwers' project will be backed by around €1 million in funding, and be supported by several industrial partners including Tata Steel. More about the research project here >>>   ---
