POLYHEED® 842N  

1. True mid-range (5-15%) water reduction and excellent performance across a wide concrete slump range
2. Increases setting time of concrete across the recommended dosage range
3. Superior workability, pumpability and finishability qualities even in concrete mixes containing low amounts of cementitious materials, and/or concrete mixes with fly ash content
4. Develops Compressive and flexural strength comparable to retarding and water reducing admixtures
5. Improved performance with a wide range of cements, fly ashes, silica fume, granulated slags, and aggregates

POLYHEED 842N meets the requirements of ASTM C494 for water reducing admixtures Type A and retarding and reducing Type D

• Reduces water content for a given slump
• Increases development of compressive and flexural strength

Features and Benefits

POLYHEED 842N aids in the production of a high quality concrete with the following particular benefits:

• Superior pumpability and workability in applications in warm weather.
• Reduces bleeding and slump
