Cementir Group launches D-Carb® for white cement decarbonisation

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 decarbonisation 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 colour 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 stabilising 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.

The introduction of D-Carb marks a profound impact on the building and construction sectors, offering a vital solution for decarbonising practices within the industry, while enhancing Cementir's portfolio of lower-carbon products. Cementir Group continues its broader decarbonisation efforts for low-carbon products, ongoing assessments are in progress to strengthen the D-Carb range with additional sustainable solutions.
