ADVA® 650

High Range Water Reducer / Superplasticizer with enhanced consistence retention performance

Product Description

ADVA® 650 is a high performance liquid superplasticiser designed for the production of ready-mixed concrete. Intended for use in a wide range of concrete applications and as well as a superplasticicing effect will also provide extended slump retention properties. ADVA®  650 is particularly beneficial for long or difficult pours. ADVA® 650 is based on next generation modified synthetic carboxylated polymers and offers concrete producers the advantages of the latest advances in concrete technology. ADVA® 650 conforms to EN 934-2 and is manufactured under controlled conditions to give a consistent product.


  • ADVA® 650 is especially suitable for producing high consistence concrete, with excellent rheology and consistence retention properties
  • Using suitable mix designs ADVA® 650 can be used to achieve extended consistence life over normal superplasticisers, even with difficult cements
  • High consistence flowing concrete can be obtained by incorporating ADVA® 650 into a concrete design for a S2 consistence and/or low water/cement ratio
  • Minimal impact on setting time
  • Suitable for use in mix designs containing fly ash, ggbs or silica fume
  • ADVA® 650 can be used to achieve high range water reduction, leading to considerable increases in compressive strength; impermeability and durability are correspondingly improved

Method Of Use

ADVA® 650 is supplied ready for use.

When producing high consistence concrete or concrete of low w/c ratio it is recommended that ADVA® 650 be added in its supplied form with part of the batching water, after the addition of the cementitious component. After the addition of admixture, a further mixing cycle of at least two minutes is suggested to enable ADVA® 650 to efficiently disperse the mix components.


With Cements :

ADVA® 650 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 Applied Technologies.

With Other Admixtures:

ADVA® 650 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. As with most products of this type, the magnitude of the effect obtained with ADVA® 650 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. 

Addition Rates

Range 500 ml -1300 ml per 100 kg cement
0.50% -1.30% (v/w) by wt. of cement
As a guide to trials an addition rate of 0.40 - 0.70% volume by weight of cement is suggested.
For advice and assistance with trials we recommend that you consult GCP Applied Technologies.

Effects of Overdosing

The effect of overdosing ADVA® 650 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 sulphate resisting cement 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. 


It is preferable that the ADVA® 650 should be introduced into the mixer by means of automatic dispensing equipment. Equipment or advice on dispensing can be obtained from GCP Applied Technologies.

Health and Safety

For further information on Health and Safety matters regarding this product we recommend that you consult the relevant Safety Data Sheet from GCP Applied Technologies. In line with general chemical handling precautions avoid contact with skin or eyes and protective gloves/goggles should be worn.


ADVA® 650 is supplied in both 15 and 205 non returnable drums and 1,000 litre totes. Alternatively, bulk deliveries can be arranged.


ADVA® 650 if possible be stored away from extremes of temperature and then protected from frost. If the product does become frozen, it should be carefully mixed after thawing out to restore it to its normal state. The product should be kept out of direct sunlight in shaded storage at all times.
