ADVA® 395 admixture is a polycarboxylate based high-range water reducer designed for the production of conventional and Self Consolidating Concrete. It is formulated to provide extended slump life along with excellent workability without segregation.
ADVA® 395 is supplied as a ready to use liquid that weighs approximately 8.9 lbs/gal (1.1 kg/L) and does not contain intentionally added chlorides.
- Excellent moisture and air control
- Extended slump retention up to one hour
- Enhanced concrete cohesiveness with low viscosity for rapid placement
- Superior finish on cast surfaces
- Excellent early and later age compressive strength
ADVA® 395 high-range water reducing admixture is a plant added superplasticizer that is formulated to impart improved workability to concrete over an extended period of time while still achieving high early age compressive strength. It can be used for the production of Self Consolidating Concrete (SCC), and may also be used in conventional concrete production.
ADVA® 395 may be used to produce concrete in applications with very low water/cementitious ratios, where concrete stability and improved tolerance to material variability are required, while maintaining high levels of workability over long periods of time.
ADVA® 395 high-range water reducer is an easy to dispense liquid admixture. Dosage rates can be adjusted to meet a wide spectrum of concrete performance requirements. Addition rates can vary from 2 to 10 fl oz/100 lbs (130 to 650 mL/100 kg) with the type of application, but will typically range from 3 to 6 fl oz/100 lbs (200 to 390 mL/100 kg) of cementitious material. Should conditions require using more than the recommended addition rate, please consult your GCP representative.
Mix proportions, cementitious content, aggregate gradations and ambient conditions will affect the product’s dosage requirements. If materials or conditions require using more than the recommended addition rates, or when developing mix designs for Self Consolidating Concrete please consult your GCP representative for more information and assistance.
Compatibility with Other Admixtures and Batch Sequencing
ADVA® 395 high-range water reducer is compatible with most GCP admixtures as long as they are added separately to the concrete mix. However, ADVA® products are not recommended for use in concrete containing naphthalene based admixtures including DARACEM®19 and DARACEM® 100. In general, it is recommended that the product be added to the concrete mix near the end of the batch sequence for optimum performance. Different sequencing may be used if local testing shows better performance. Please see GCP Technical Bulletin TB-0110, Admixture Dispenser Discharge Line Location and Sequencing for Concrete Batching Operations for further recommendations.
Pretesting of the concrete mix should be performed before use and as conditions and materials change in order to assure compatibility with other admixtures, and to optimize dosage rates, addition times in the batch sequencing and concrete performance. For concrete that requires air entrainment, the use of an ASTM C260 air entraining agent (such as DARAVAIR® or DAREX® product lines) is recommended to provide suitable air void parameters for freeze thaw resistance. Please consult your GCP representative for guidance.
Packaging & Handling
ADVA® 395 high-range water reducer is available in bulk, delivered by metered trucks, in 275 gal (1040 L) totes, and 55 gal (210 L) drums. ADVA® Cast 395 will freeze at approximately 32°F (0°C) but will return to full functionality after thawing and thorough mechanical agitation.
A complete line of accurate, automatic dispensing equipment is available.
