Using more sludge and less slag in their recipe, researchers were able to create a material that's stronger than even today's ...

with no need for a combustion furnace or electric heating. Sublime claims it's, "the only fossil-fuel-free, scalable, drop-in replacement for traditional cement in concrete." A few days ago ...

and its emissions from that industry far outpace those generated by its domestic steel or cement production. In part, this is because the U.S. relies more heavily on electric arc furnaces to make ...

The method, which the researchers say is 'an absolute miracle', uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, the carbon-hungry component of ...

heating the cement would remove the water, and then it would form clinker again,” he said. “A bath of liquid metal would help this chemical reaction along, and an electric arc furnace ...

The furnace holds a 230mm tall crucible of 180mm in diameter, it should hold 35kg of aluminum. Insulation from the inside out is composed of: refractory cement, ceramic wool, glass wool.

“A key insights from our study is the potential of MSWI FA, when combined with blast furnace slag (BFS ... a viable alternative to traditional cement in various industrial applications.” ...

Recycling cement would massively reduce its carbon footprint. Researchers say that if they switched to electric-powered furnaces, and used renewable energy like wind and solar rather than fossil ...
