MasterCO₂re is an innovative superplasticizer which combines the performances of fluidification, extended workability retention, high early and ultimate strength with excellent rheology in one single solution. This advanced technology provides a perfect choice for stable and robust concrete performance in challenging low-clinker applications, paving the way for a more responsible future in the construction industry.

MasterCO2re offers the following main benefits to precast producers:

• Extended workability retention: MasterCO₂re releases the polymer over time, ensuring consistent workability of concrete.

• Advanced rheology: concrete containing MasterCO₂re has a very low viscosity. This allows good workability and flowability during casting even with concrete using a difficult cement such as low clinker cement or concrete formulated with high SCM content for instance.

• Strength properties: Thanks to the very good rheology provided by ICS technology of MasterCO₂re, the content of water in the concrete recipe can be further reduced. This allows the achievement of the early strengths needed to meet the production requirements even in concrete mixes with reduced clinker amount. MasterCO2re promotes the formation of a denser and more homogeneous structure of cement hydrates, which is reflected in optimal strengths development.

• Superb robustness: with rapidly changing cement types and binder compositions, the stability and quality consistency of concrete is a challenge in precast plants’ daily operations. MasterCO₂re successfully counteracts the potential of high-water absorption and other undesirable effects caused by the variation in the chemical and mineralogical composition of the binders.

Additionally in precast concrete mixes where the amount of clinker is significantly reduced (above 15%), MasterCO₂re can be used in combination with Master X-Seed®. The synergistic effect of the two admixtures allows a further boost to the early strength development required for fast demoulding of the elements to achieve the desired production output
