D-Carb White cement

Cementir Group has introduced D-Carb®, a new generation of white cement designed to support decarbonisation in the construction sector. The first product in the range, CEM II/A-LL 52.5R, offers a 15% reduction in CO₂ emissions compared to traditional Aalborg White® CEM I 52.5R, while maintaining high early strength and visual quality.

Engineered with a synergy of Aalborg White® clinker and pure limestone, D-Carb® delivers excellent rheological properties and early-age strength, ideal for applications such as self-compacting and wet-cast concrete. Enhanced fineness and particle size distribution ensure smooth, marble-like finishes without compromising on performance.

Despite replacing part of the clinker with limestone, D-Carb® maintains the hallmark features of Aalborg White®: low alkali and chloride content, strong durability, and high whiteness. It integrates smoothly into existing production processes with minimal adjustments and is compatible with a wide range of admixtures.

Following a successful launch in Europe, D-Carb® has received positive feedback from industrial users, particularly in precast and ready-mix concrete applications. Trials confirmed strong performance and ease of transition from CEM I 52.5R, helping manufacturers lower their carbon footprint without sacrificing quality.
