ADVA 971 is a liquid mid range Polycarboxylate ether based admixture essentially designed to work in ready mix concrete mixes with low binder contents.
ADVA 971 is specially formulated to offer adequate water reduction, prolonged slump retention and early set times, better compressive strengths in contrast to conventional naphthalene products.
ADVA 971 works effectively across both natural and crushed fine aggregates in a range of concrete grades starting from a least binder content.
ADVA 971 conforms to IS 9103, ASTM C494 Type A, D and Type F & G admixtures, and EN 934-2.
Method Of Use
ADVA 971 is supplied ready for use. It should be added in its supplied form to the concrete after at least 90% of water is added.
Compatibility with Cements
ADVA 971 can be used with most types of Portland Cements. It is effective in concretes containing pulverized fuel ash or ground granulated blast furnace slag.
For use with special cements we recommend to contact GCP Applied Technologies
- Can replace conventional naphthalene admixtures used in ready mix concrete
- Has a good dosage range to work over different types of mixes to offer desired performance
- Retains slumps for longer times with minimal retardation in contrast to conventional naphthalene admixtures
- Performs well with flyash mixes and also mixes containing ggbfs
- Can produce highly workable / self levelling mixes
- 300 ml -1300 ml per 100 kg cement
- 0.30% -1.30% (v/w) by wt. of cement
As a guide to these trials, an addition level of 0.3-1.3 % ADVA 971 volume by weight of cement is recommended.
For advice and assistance with trials we recommend that you consult GCP Applied Technologies.
ADVA 971 is a versatile, high performance product that benefits from a wide variety of applications. As with most products of this type the magnitude of the effect obtained with ADVA 971 is governed by the quantity of product used, water-cement ratio, and the specific nature of the concrete and constituent materials.
It is necessary, therefore, to assess performance under site conditions using actual materials to determine optimum performance and dosage and effect on both plastic and hardened concrete properties such as cohesiveness, workability retention, setting characteristics, rate of early strength gain, ultimate strength and shrinkage where these are of consequence.
Compatibility with Other Admixtures
ADVA 971 is permitted to use along with compatible DARATARD versions for slump retention purposes.
For such applications, we recommend to contact GCP Applied Technologies.
Effects of Overdosing
The effects of overdosing ADVA 971 are a function of the degree of overdose.
Depending on the extent of the overdose, an increase in setting time may also occur, especially in low temperatures, and or when employing sulphate resisting cement, or certain pozzolanic materials.
In any situation where overdosing is suspected, a careful inspection of the concrete in its plastic state should be conducted. Particular attention should be paid to consistency and cohesiveness, prior to a decision on the suitability of the concrete for the particular application.
It is preferable that ADVA 971 should be introduced into the mixer by means of independent automatic dispensing equipment.
Equipment or advice on dispensing can be obtained from GCP Applied Technologies.
