Cambridge University researchers have conducted the first scrap-metal trial melt in the Materials Processing Institute (MPI) Cement 2 Zero project, aiming to prove the potential of cement clinker production using graded, recycled concrete material as flux in electric arc furnace (EAF) steel milling. The project entails a collaboration of MPI and Cambridge; construction materials producers CELSA Steel UK, Day Aggregates…

Researchers convert post-service life cement paste to new slag binder
Sources: Materials Processing Institute, Middlesbrough, U.K.; CMCM staff The United Kingdom’s Materials Processing Institute is testing the potential to transform finely graded cement paste, extracted from demolition concrete, to new cementitious material using scrap steel melted by an electric arc furnace. Dubbed Cement 2 Zero, the two-year project could prove at commercial scale the Cambridge Electric Cement (CEC) process developed…
