Cementir Group Launches D-Carb for White Cement Decarbonization

Cementir launches today a new Aalborg White Cement with a lower carbon footprint, D-Carb, which presents a 15 percent reduction in CO2 emissions when compared with CEM I 52.5R. D-Carb is the first white cement in the market to match a lower-carbon footprint with high performances at early ages. It is available in European markets before being launched globally.

“We are thrilled to introduce D-Carb, our new umbrella brand for lower carbon cements, as part of Cementir Group’s ongoing commitment to address environmental challenges and climate change.” says Michele Di Marino, Chief Sales, Marketing, & Commercial Development Officer of Cementir. “As a leading white cement producer, the successful rollout of D-Carb® is pivotal in advancing our “net-zero emissions” ambition. Embracing a customer-centric approach, the unveiling of this product is eagerly anticipated. D-Carb®, integrating lower-carbon, high performance and unique aesthetic value, underscores our resilience in facing challenges in our decarbonization efforts. We believe that D-Carb will further support stakeholders in the value chain with lower-carbon finished products aligned with sustainable building standards. ”

The synergy between well-known Aalborg White clinker and pure limestone has been optimised by choosing a fit-for-purpose grinding aid to achieve comparable performances to our CEM I 52.5R at early ages, meeting the strict requirements of construction timelines.

D-Carb also inherits the extra properties given by the Aalborg White clinker used, extremely low alkali and low chloride content, ensuring reliable quality and durability of the finished products.

“Performances and white color are key features of D-Carb, and exploring suitable raw materials and their combinations have been crucial in the product assessment. This has resulted in the accurate selection of pure, very light limestone from a stable source, improving and stabilizing whiteness. Additionally, leveraging limestone fineness and particle size distribution, D-Carb ensures enhanced and consistent rheology, ideal for wet-cast applications, such as self-compacting concrete. These distinctive rheological properties allow for concrete finishes resembling marble surfaces. Moreover, the enhanced synergy and compatibility between cement and admixture cater to a wide range of white cement applications.” explains Stefano Zampaletta, Group Product Development Manager.

Leveraging on its peculiar performances achieved by D-Carb and after a specific testing program on site, customers are able to replace CEM I 52.5R in their manufacturing processes, especially when early age performances are the main targets. Cementir will support this sustainable transition with its technical experts to guide users in adopting D-Carb product and integrating it into their production processes.
