POLYHEED® 844R
POLYHEED 897 is a multi-component, chloride free, mid-range water-reducing admixture, formulated to produce:
. - A mid range water reduction (5 a 15%) and excellent performance through a wide range
- Increase of setting time throughout the long range of recommended dosage
- Improved workability, pumpability and finishability, even in concrete mixes containing reduced amount of cementitious materials and/or concrete mixes containing fly ashes.
- Comparable compressive strength development of that of water-reducing and retarding admixtures
Better performance with wide range types of cements, fly ashes, slags and aggregates - POLYHEED 897 admixture meets ASTM C 494 for Type A retarding admixtures, for Type B water-reducing admixture and for Type D water-reducing and retarding admixtures.
FEATURES
- Reduces water content for a given slump
- Improved time setting features
- Increased development of compressive and flexural strengths
BENEFITS
POLYHEED 897 helps produce a quality concrete with the following special benefits:
- • Superior workability and pumpability in worm weather applications
- • Reduced bleeding and slump
- • Improves finishability in flat, formed or extruded surfaces.
- • Consistent performance in concrete mixes with low, mid-range of 150 to 200mm and high concrete slumps.
