|Description||Ozone PC-1680 is a polycarboxylate base accelerating and water-reducing admixture for concrete. It
improves the plastic and hardened properties of concrete such as workability, compressive and flexural
strengths. It is a selected polymer technology-based material, specially designed for cold weather
|Primary Application||Cold weather concreting.
Concrete pipe and many pre-cast items.
|Advantages||Increased high early & ultimate strength.
Ideal for fast form stripping.
Cuts construction cost – no cold weather delays.
Minimizes bleeding and segregation.
|Specifications||Complies with ASTM C-494 Type F.|
|Packaging||210 Ltr. drums, 1000 Ltr. totes and bulk.|
|Storage||Store in a dry and cool place below 35°C. Protect from direct sunlight.|
|Shelf life||12 months if stored properly in original unopened packaging.|
|Instruction for use||Dosage: 1.0-2.0 Ltr/100kg of cement. It is advisable to carry out trial mixes to establish the exact dosage
Dispensing: Ozone PC-1680 should be added to gauging water prior to its addition to the dry mix
concrete or separately to the freshly mixed concrete. When added separately to the freshly mixed
concrete further mixing time of 2-3 minutes should be given.
Placing: The standard rules of good concreting practice for production and placing must be observed
when using Ozone PC-1680 concrete.
Curing: Fresh concrete must be cured properly. Use Ozone CureCrete or wet hessian.
Compatibility: Ozone PC-1680 is compatible with all types of cement.
Effect of overdosing: When accidental overdosing occurs, the retardation of initial set air content and
workability increases. During this period the concrete must be kept moist in order to prevent premature
