ADVA® Cast 203 is a polymer-based high range water-reducing admixture that is specially designed for producing superior early strength concrete in precast applications. ADVA Cast 203 is formulated to comply with the chemical admixture specification for concrete: ASTM C 494 as Type F; BS EN 934 - 2 : 2001 and SS EN 934-1 : 2008.
ADVA Cast 203 contains no added chloride. One litre weighs approximately 1.05kg ± 0.02kg.
ADVA Cast 203 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 203 exceeds that of normal water-reducing admixtures (Type WR) and high range water reducers (Type HWR), resulting in lower dosages and better performance.
ADVA Cast 203 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 203 can vary with type of application, but will normally range from 400 to 1,800mL / 100kg of cementitious material. In most instances, the addition of 400 to 1,400mL / 100kg of cementitious material will be sufficient. Should conditions require using more than recommended addition rates, please consult your local GCP representative.
ADVA Cast 203 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 203 should not be used with naphthalene-based products.
Please refer to ADVA Cast 203 Material Safety Data Sheet or consult GCP Applied Technologies.
ADVA Cast 203 is available in 205L pails and in bulk. ADVA Cast 203 contains no flammable ingredients.
Enhancement ADVA Cast 203 accelerates cement hydration at a very early stage. Together with the very efficient dispersion effect, ADVA Cast 203 achieves very high early strength for the production of precast structural elements.
ADVA Cast 203 is ideal for precast applications, where high early strength is desired, and where high workability will aid faster placement and improved mix consolidation.
ADVA Cast 203 produces concrete with superior surface finish, without stickiness, tearing or spotty set characteristics.
With up to 40% water reduction possible, ADVA Cast 203 is highly effective in low water-cement concrete, producing high strength and high early strength precast concrete.
Production The very neutral set times of ADVA Cast 203 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.
