Description Ozone LD 430 is a ready to use naphthalene based, high range water-reducing and slump retention
admixture for concrete. Ozone LD 430 increases early concrete strength as well as ultimate strength.
Ozone LD 430 can be used to produce increased concrete slump or to significantly reduce water demand
for a specific slump.
Primary Application High-performance concrete.
Self-compacting concrete.
Precast concrete.
Low water/cement ratio concrete.
High early & ultimate strength applications.
Advantage Improve resistance to freeze-thawing and excellent protection against steel bar protection used in
Substantial improvement in workability without increased water.
Long-lasting control of slump loss.
It provides high early strength for fast form stripping.
Specially suitable for hot climates.
Densifies concrete.
Minimizes bleeding and segregation.
Specifications Complies with ASTM C-494,Type F & G.
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.
Appearance Brown liquid
Specific gravity 1.12 at 20°C
Chloride content Nil to BS 5075
Air entrainment Less than 2% at normal dosage
Instruction for use Dosage: 0.4-0.8 Ltr/100kg of cement. It is advisable to carry out trial mixes to establish the exact dosage
rate required.
Dispensing: Ozone LD 430 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 LD 430 concrete.
Curing: Fresh concrete must be cured properly. Use Ozone Cure Crete or wet hessian.
Compatibility: Ozone LD 430 is compatible with all types of cement.
Effect of overdosing: When accidental overdosing occurs, the retardation of initial set air content and
workability increases. It is strictly advised that the dosage should be as per the datasheet.
