US: CalPortland has announced the launch of Advancement, a product line of cements containing sustainable materials and produced using renewable processes. These include the replacement of 15% of the Ordinary Portland Cement (OPC) clinker with blended limestone. The company currently offers Advancement Light for aesthetic design and Advancement High Sulphate for general use concrete applications and when high sulphate resistance is required, both of which have 10% lower embodied carbon than OPC. More products are planned to follow.
CalPortland president and chief executive officer (CEO) Allen Hamblen said, “Advancement is a line of products that can be combined with other concrete carbon reduction technologies to further enhance performance and increasingly reduce the embodied carbon of concrete.”
