A new electrochemical process for making cement has been developed by researchers at MIT. Although the process isn’t ready to scale yet, the potential to reduce greenhouse emissions from this critical building material is immense.
Cement is currently responsible for 8% of global greenhouse gas emissions because the typical process for making Portland cement requires coal to heat a limestone, sand, and clay mixture. This new process uses an electrolyzer and carbon sequestration to substantially improve the environmental impact of cement.
Cement has been an essential part of civil engineering works as a foundational building block used in the subdisciplines of civil engineering to construct large projects, provide structural support for buildings and bridges, carry traffic volumes on roads, and countless other applications. – Daniel Findley, DTC Civil Transportation Instructor
