Reducing the clinker content in concrete is an important sustainability goal in the construction industry, as clinker production is a major source of carbon dioxide emissions. Various admixture solutions can be employed to optimize the performance of low-clinker concrete while maintaining or improving its properties. Our range of MasterCO2re concrete admixtures are based on an Intelligent Cluster System (ICS) which releases its dispersing effect over time providing added benefits to the low-clinker concrete mix.

MasterCO2re offers the following main benefits to ready mix producers:

• 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.

• 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.
