In fact, blast-furnace slag is already commonly used as a partial replacement for cement. By contrast, EAF slag has historically been less useful as a cement replacement and is generated in much ...

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 ...

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 ...

Throwing old concrete into steel-processing furnaces not only purifies iron but produces “reactivated cement” as a byproduct. If done using renewable energy, the process could make for ...

Concrete is widely used for making sewage pipes due to its availability, affordability and structural strength, but it is ...

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 ...

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 ...
