POLYHEED 861HE is a ready to use liquid admixture. It is primarily formulated to provide water reduction and acceleration to the setting time of concrete under cold winter conditions. It provides high early strength in special application concrete, while water reduction and workability retention of the fresh concrete are improved compared to previous technologies. It does not contain added chloride and conforms to chloride ion limits required by concrete industry standards.
Polyheed 861HE complies with ASTM C-494 for Types C and E admixtures.
POLYHEED 861HE is recommended for any concrete that requires short setting time characteristics and early strength, superior workability, pumpability and finishability. Typical application fields are housing, bridges, concrete highway as well as manufactured concrete products. Particularly suitable when smooth surface of the concrete is required. It is also applicable in concrete subject to chloride ion constraints such as in coastal environments.
