ADVA® Cast 207
High early strength polymer-based superplasticiser for precast concrete
ADVA® Cast 207 is a polymer-based high range water-reducing admixture that is specially designed for producing superior high early strength concrete in precast applications. ADVA Cast 207 contains no added chloride. It is formulated to comply with specifications for chemical admixtures for concrete: ASTM C 494, Type F. One litre weighs approximately 1.10kg ± 0.02kg.
ADVA Cast 207 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 207 exceeds that of normal water-reducing admixtures (Type WR) and high range water reducers (Type HWR), resulting in lower dosages and better performance.
- Superior early strength enhancement
- High workability
- Superior surface finish
- Superior water reduction
- Optimise precast concrete production
ADVA Cast 207 produces concrete with high early strength for precast concrete elements, while at the same time achieving high workability for easy and fast placement of concrete. It also allows concrete to be produced with very low water-cement ratios in low to high slump ranges.
Addition rates of ADVA Cast 207 can vary with type of applications, but will normally range from 200 to 700mL / 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.
ADVA Cast 207 is compatible with most water-reducing admixtures as well as specialty admixtures like accelerators, DCI® Corrosion Inhibitor, Eclipse® shrinkage-reducing admixture and V-MAR® rheology-modifying admixture. 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. ADVA Cast 207 should not be used with naphthalene-based products.
Please contact your local GCP representative for further information regarding the dispensing equipment for this product.
ADVA Cast 207 is available in 205L pails and in bulk. ADVA Cast 207 contains no flammable ingredients.
Superior Early Strength Enhancement
ADVA Cast 207 accelerates cement hydration at a very early stage. Together with the very efficient dispersion effect, ADVA Cast 207 achieves very high early strength for the production of precast structural elements.
ADVA Cast 207 is ideal for precast applications, where high early strength is desired, and where high workability will aid faster placement and improved mix consolidation.
Superior Surface Finish
ADVA Cast 207 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 207 is highly effective in low water-cement concrete, producing high strength and high early strength precast concrete
Optimise Precast Concrete Production
The very neutral set times of ADVA Cast 207 may reduce or 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 total costs and increased productivity.
