Concrete production accounts for about 8% of man-made CO2 emissions worldwide, of which up to 90% is due to cement clinker production. Substituting clinker contained in cement and ultimately in concrete with alternative materials such as limestone filler or supplementary cementitious materials (SCMs) can save considerable amounts of carbon emissions. However, these more sustainable materials do not come without their own challenges and influence the concrete properties:
Loss in workability, worsening of rheology, and the reduction of strength. 
                  

The intelligent cluster system MasterCO2re overcomes performance gaps associated with low-clinker concrete production supporting our customer's demanding process to reduce clinker and achieve sustainable concrete performance.

Superb Workability Retention

Thanks to the intelligent cluster system, MasterCO2re™ releases the polymer over time, ensuring consistent flowability and workability during concrete transport and placement.

Advanced Rheology

Concrete with the advanced MasterCO2re™ technology has a lower viscosity than conventional superplasticizers. As a result, concrete is easier and faster to pump and place. The water content can be further reduced without affecting the rheological properties, even in concrete mixes with reduced clinker content.

Excellent Strength Properties

MasterCO2re™ promotes the formation of a dense and homogeneous structure of cement hydrates, resulting in optimal strength development.

Unmatched Robustness

With rapidly changing cement types and binder compositions, the stability and quality consistency is a challenge in the daily operation of concrete plants. MasterCO2re™ successfully counteracts the potential of high-water absorption and undesirable interactions with admixtures caused by variations in the chemical and mineralogical composition of binders.

MasterCO2re™
is a game-changing technology based on an intelligent cluster system (ICS) that delivers its effects precisely when required. A portion of its freely available polymers is immediately dispersed for initial water reduction. The finely tuned chemical structures of the diverse clusters optimise both workability retention and cement hydration by adapting the polymers' release mechanism to the cement matrix's characteristics.

MasterCO2re™ reliably ensures excellent flowability and rheology even at high temperatures, allowing easy pumping and placing of concrete.
