Product Description
ADVA® FLOW 602 is a high efficiency, new generation liquid superplasticiser designed to yield high range water reduction, short setting time, high consistence and high early compressive strength concrete as required by the precast industry.
ADVA® FLOW 602 is ideal for use in all precast / pre-stressed structures where high range water reduction is desired for strength development and/or heat energy savings. It is suitable for the production of very high flow and self-compacting concrete suitable for use around reinforcement without blocking or segregating.
ADVA® FLOW 602 is based on next generation modified synthetic carboxylated polymers and is manufactured under controlled conditions to give a consistent product. ADVA® FLOW 602 conforms to EN 934-2.
Advantages
- ADVA® FLOW 602 is especially suitable for producing high range water reductions, allowing considerable increases in compressive strength
- ADVA® FLOW 602 is extremely dose efficient, allowing the production of very high flow and self-compacting concrete without excessive admixture dosage and at ‘normal’ water contents
- ADVA® FLOW 602 provides improved impermeability and durability characteristics with reduced defects
- Dose efficient with linear water reductions
- High consistence flowing concrete can be obtained with excellent rheology and handling properties
- Improved concrete cohesion
- Suitable for use in mix designs containing fly ash, ggbs or silica fume

Method Of Use
ADVA® FLOW 602 is supplied ready for use.
When producing high consistence concrete or concrete of low w/c ratio it is recommended that ADVA® FLOW 602 be added in its supplied form with part of the batching water, after the addition of the cement. After the addition of admixture, a further mixing cycle of two minutes is suggested to enable ADVA® FLOW 602 to efficiently disperse the mix components.
Compatability with Cements
ADVA® FLOW 602 can be used with most types of Portland cements. It is also effective in concrete containing fly ash or ground granulated blastfurnace slag.
For use with special cements we recommend contacting GCP
Compatability with Other Admixtures
ADVA® FLOW 602 should not under any circumstances be premixed with other admixtures. The performance of the product will be affected by the presence of other chemical admixtures.
We recommend that all admixtures be added separately into the mix.
Addition Rates
Range |
400 ml -1000 ml per 100 kg cement |

0.40% -1.00% (v/w) by wt. of cement |
As a guide to trials an addition rate of 0.60-0.80% volume by weight of cement is suggested. |
As with most products of this type, the magnitude of the effect obtained with ADVA® FLOW 602 is governed by the quantity of product used, w/c ratio, and specific nature of the concrete and constituent materials. It is necessary therefore to assess performance under site conditions using actual materials to determine optimum dosage and effect on plastic/ hardened concrete properties, such as cohesiveness, consistence retention, set characteristics, early rate of strength gain, ultimate compressive strength and shrinkage when these are of consequence.
Effects of Overdosing
The effect of overdosing ADVA® FLOW 602 is a function of the degree of overdose.
When producing high consistence concrete, overdosing will increase the level of consistence and may induce the onset of segregation.
Depending on the extent of the overdose, an increase in setting time may also occur, especially in low ambient temperatures and/ or when employing Sulfate-resisting Portland cements or cement replacement materials.
Any situation where an overdose is suspected, careful inspection of the concrete in its plastic state should be conducted. Particular attention to consistency and cohesiveness prior to a decision on the suitability of the concrete for the particular application in question.
Dispensing
It is preferable that ADVA® FLOW 602 should be introduced into the concrete mixer by means of automatic dispensing equipment.
Equipment or advice on dispensing can be obtained from GCP Applied Technologies.
