ADVA® Cast 560

Accelerating High Early Age Strength Concrete Superplasticiser for Precast Applications

Product Description

ADVA® CAST 560 is an accelerating superplasticiser admixture to yield high range water reduction, short setting time and very high early compressive strength as required by the precast industry ADVA® CAST 560 superplasticiser allows concrete to be produced with low water/cement ratios and consequently gives rise to very high early (12-24 hours) and final compressive strength. ADVA® CAST 560 is ideal for use in all precast / pre-stressed structures where high range water reduction and accelerated early strength development are needed for early de-moulding and/or heat energy savings.

ADVA® CAST 560 is based on synthetic carboxylated polyether and conforms to British Standard EN 934-2 and manufactured under controlled conditions to give a consistent product.

Advantages

  • ADVA® CAST 560 is especially suitable for producing high range water reductions, allowing considerable increases in compressive strength.
  • ADVA® CAST 560 provides improved impermeability and durability characteristics with reduced defects
  • ADVA® CAST 560 can be used to reduce the energy requirements of external heat in accelerated curing
  • 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® CAST 560 is supplied ready for use.

When producing high consistence concrete or concrete of low w/c ratio it is recommended that ADVA® CAST 560 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® CAST 560 to efficiently disperse the mix components.

Compatibility

With Cements :

ADVA® Cast 560 is supplied ready for use. When producing high workability concrete it should be added with part of the batching water, ater the addition of the cementitious component. It should not be added directly to the cement.

After the addition of ADVA® Cast 560, a further mixing cycle of at least 2 minutes is recommended to fully disperse the mix components.

Compatibility

With Cements:

ADVA® CAST 560 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® CAST 560 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 700 ml - 2000 ml per 100 kg cement
0.70% - 2.00% (v/w) by wt. of cement
As a guide to trials an addition rate of 1.50% volume by weight of cement is suggested.
For advice and assistance with trials we recommend that you consult GCP Applied Technologies.

As with most products of this type, the magnitude of the effect obtained with ADVA® CAST 560 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® CAST 560 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, or if the water content is adjusted accordingly allowing even greater water reduction which causes the mix to become overly cohesive. Only when there are large overdoses will an increase in setting time be significant. 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® CAST 560 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.

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.

Packaging

ADVA® CAST 560 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.

Storage Life in Manufacturer’s Drums:
