ADVA ® Cast 700

Product Description

ADVA ®  Cast 700 is a third generation polycarboxylic high range water-reducing admixture that is specially designed for producing superior high early strength concrete in precast applications.

ADVA Cast 700 contains no added chloride. It is formulated to comply with specifications for chemical admixtures for concrete: AS 1478 as a Type HWR. One litre weighs approximately 1.070kg ± 0.02kg.

Product Advantages

• Superior early strength enhancement 
• Extended slump retention (up to 60 minutes) 
• High workability
• Superior surface finish 
• Superior water reduction
• Optimise precast concrete production 
• Precast concrete batched off-site

Dispersion

ADVA Cast 700 is a superior dispersing admixture, having a marked capacity to disperse cement agglomerates normally found in a cement-water suspension. The capability of ADVA Cast 700 exceeds that of a normal High Range Water Reducers (Type HWR), resulting in lower dosages and better control.

Uses

ADVA Cast 700 produces concrete with high early strength for precast structural elements, while at the same time achieving high workability for easy and fast placement and consolidation. It also allows concrete to be produced with very low water-cement ratios in low to high slump ranges.

Advantages

Extended Slump Retention

ADVA Cast 700 has been developed to offer enhanced slump life to concrete. This extended slump life will be very important for concrete placed in large precast units or in high temperature regions.
ADVA Cast 700 can also be used in concrete produced off-site and transported to the pre-cast yard.

Superior Early Strength Enhancement

ADVA Cast 700 accelerates cement hydration at a very early stage. Together with the very efficient dispersion effect, ADVA Cast 700 achieves very high early strength for the production of precast structural elements.

High Workability

ADVA Cast 700 is ideal for precast applications, where high early strength is desired, and where high workability will aid faster placement and improved mix consolidation. Ideally suited for self- compacting concrete or super workable concrete applications.

Superior Surface Finish

ADVA Cast 700 produces concrete with superior surface finish, without stickiness, tearing or spotty set characteristics.

Superior Water-Reduction

With up to 40% water reduction possible, ADVA Cast 700 is highly effective in low water-cement concrete, producing high early strength concrete.

Optimise Precast Concrete Production

The accelerated set times of ADVA Cast 700 may help to eliminate the need for heat curing to achieve high early strength concrete. The earlier removal of forms leads to reduced cycle times, faster mould turnaround, reduced costs and increased productivity.

Addition Rates

Addition rates of ADVA Cast 700 can vary with type of applications, but will normally range from 200 to 1000mL / 100kg of cementitious material. In most instances, the addition of 300 to 600mL / 100kg of cementitious material will be sufficient. Should conditions require using more than recommended addition rates, please consult your local GCP representative.

Compatibility

ADVA Cast 700 is compatible with most water-reducing admixtures as well as specialty admixtures like accelerators, DCI ®  Corrosion Inhibitor, Eclipse ®  Shrinkage-Reducing Admixture and V-MAR ®  3 Rheology-Modifying Admixture. However, it cannot be used in conjunction with DAREX ®  Super 20, DARACEM ® , DARACEM19A or any other NSFC based superplasticiser. All admixtures should be separately added to the concrete. Pre-testing of the concrete should be performed to optimise dosages and addition sequence of these admixtures.

Dispensing Equipment

Please contact your local GCP representative for further information regarding the dispensing equipment for this product.

Packaging

ADVA Cast 700 is available in bulk.

ADVA Cast 700 contains no flammable ingredients. It will begin to freeze at approximately 0ºC, but will return to full strength after thawing and thorough agitation.

In storage, and for proper dispensing, ADVA Cast 700 should be maintained at temperatures above 0ºC.
