Alternative clinkers

The drive to lower the carbon footprint of cement has led to the development of alternative cement clinkers to replace Portland cement clinker. Arthur Harrisson examines the potential of carbon reduction in four alternative clinker types, as proposed by Gartner and Sui. Belite in clinker Some years ago in ICR the possibilities for using alternatives to Portland cement clinker were...
