POLYHEED® 867
POLYHEED 867 is a multicomponent mid-range
water-reducing admixture, free of chlorides, designed to produce:
- Mid-range water reduction (5 to 15%) and
an excellent performance through a wide slump range, especially in difficult
concrete slump ranges such as 150 to 200 m.
-
Increases the setting time of concrete
along the recommended dosage range .
- Improves workability, pumpability and
finishing even in mixes with low content of cementitious materials and/or of
mixes containing fly ash.
Development of comparable strengths with
water reducing and retarding admixtures.
-
Better performance with a wide range of
cements, fly ash, aggregates and granulated slag.
Characteristics
-
Reduces the content of water for a given
slump
- Enhances setting time features.
- Increase compressive and flexural strength
development.
Benefits
POLYHEED 867 helps to produce a quality concrete
with the following special benefits:
- Superior workability and pumpability in
applications in warm climates.
- Reduces the bleeding and segregation.
- Improves finishing characteristics in
flat, poured and extruded surfaces. (extruding machines).
- Consistent performance in concretes with
low slumps, mid range slumps of (150 to
200 mm) and high range slumps.
Applications
POLYHEED 867 is recommended for any concrete
where extend setting time, workability and superior finish is required,
particularly in warm climates. POLYHEED 867 can be used in architectural
concrete and colored concrete.
POLYHEED 867 can be used with air entraining
admixtures, as long as the ASTM, AASHTO and CRD specifications are met.
