High-range water-reducing admixture for concrete – EN 934-2: T3.2
MasterPolyheed 415 is an innovative ready-to-use high-range water-reducing admixture that results in concrete with different levels of workability for applications such as pumping and flatwork. It allows water reduction while maintaining workability, increasing strength, durability and impermeability.
MasterPolyheed 415 is very effective in producing concrete with enhanced finishing characteristics. It has been formulated to permit increased replacement levels of natural sands with crushed rock fines.
Where to use MasterPolyheed 415?
Use MasterPolyheed 415 in concrete mixes to increase and extend workability, increase compressive strength and bring cement economies.
It can also be employed to good effect where there are areas of congested reinforcement, meaning that high workability is beneficial.
Further uses include to reduce water contents and in hot weather to extend workability.
What makes MasterPolyheed 415 different?
MasterPolyheed 415 is based on MasterGlenium technology and permits a wide dosage range, enabling water reductions for a dense concrete with reduced permeability and water penetration.
It can be used in a wide variety of concrete mixtures as a multi-purpose admixture, and its dosage flexibility gives a water reduction of up to 25%.
Better slump retention and enhanced later-age strength are accompanied by excellent finishability, even with manufactured sands and in lean mixes.
MasterPolyheed 415 significantly improves a concrete’s workability, reducing placing time. It enhances the concrete’s cohesiveness, helping to reduce segregation and bleed.
Economies in mix designs can be achieved through MasterPolyheed 415. The admixture improves strengths in mixes containing PFA, GGBS, Portland Limestone and micro-silica blends.
Faster setting at higher dosages is possible compared to other water-reducing admixtures in the same category. In practical terms, MasterPolyheed 415’s use results in lower in-place cost, and increases the service life of structures.
