​MasterPolyheed 8861 - New generation mid-range water reducer

How does MasterPolyheed work?

MalsterPoyheed 8861 is a multi-component, non-chloride, mid-range water reducing admixture designed to improve the performance of concrete both in the pastic and hardened states. It is a versatile admixture able to produce mid-range slumps without retardation. Its formulation contains materials able to improve the conrete's rheology, strength and finishability.

What are the recommended uses of MasterPolyheed 8861?

• All types of concrete where a non-chloride water reducing admixture is required, especially in the slump band (80-150mm)
• Improving the performance of pumped concretem shotcrete and conventionally placed concrete
• Ready mixed concrete using manufactured sands
• Long-distance transporting
• Pumped concrete
• High workability without segregation or bleeding
• High performance concrete for durability

Whare are the features and benefits of MasterPolyheed 8861?

• Good dispension in mixes with high manufactured sand contents
• High workability for longer periods
• Lower pumping pressure with manufactured sands
• Resistance to segregation even at high workability
• Extended setting with longer workability
• Reduced water content for a given workability
• Higher ultimate strengths
• Increased ease in finishing concrete with poor aggregates/gap graded aggregates

Chemistry and mechanism of action is what differentiates MasterPolyheed 8861 from the traditional admixtures, being a new, unique mechanism of action that greatly improves the effectiveness of cement dispension coupled with rheology improvement.
