Polyheed 700R 

POLYHEED 700R is a non-chloride, mid-range water-reducing and retarding admixture which is formulated to produce:

1. true mid-range (5-15%) water reduction and excellent performance across a wide slump range (150-200 mm).

2. extended concrete setting time characteristics throughout the recommended dosage range

3. superior workability, pumpability and finishability qualities even in concrete mixes using low amounts of cementitious materials and/or fly ash mixes

4. strength performance comparable to water-reducing and retarding admixtures at all ages

5. improved performance with a wide range of cements, fly ashes, granulated slags, and aggregates (including coarse and manufactured sands).

POLYHEED 700R has been formulated to meet the requirements of ASTM C494 for Types B and D admixtures, specifically:

• reduced water content for a given slump
• extended setting time characteristics
• increased compressive and flexural strength performance at all ages
• improved concrete durability to damage from freezing and thawing
• reduced shrinkage

POLYHEED 700R is compatible with all cements meeting the recognised international standards.
