Silicate-derived calcium as a pathway to low-carbon Portland cement
A new study explores the potential of using silicate-derived calcium from basalt to produce low-carbon Portland cement. This method could significantly reduce greenhouse gas emissions associated with traditional cement production, which currently accounts for 4.4% of global emissions. The research indicates that this alternative could lower energy demands by 30% and eliminate process emissions entirely.
- ▪Cement production is responsible for 4.4% of global greenhouse gas emissions.
- ▪Using basalt instead of limestone for Portland cement could reduce energy requirements and emissions.
- ▪The proposed method could lower total energy demand by 30% compared to conventional production.
