ADVA® Cast 3738 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 3738 contains no added chloride. It is formulated to comply with specifications for chemical admixtures for concrete: ASTM C 494, Type F; BS EN 934-2: 2001 and SS EN 934–2: 2008.
One litre weighs approximately 1.07 ± 0.02kg.Dispersion
ADVA Cast 3738 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 3738 exceeds that of normal water-reducing admixtures (Type WR) and high range water reducers (Type HWR), resulting in lower dosages and better performance.
Addition rates of ADVA Cast 3738 can vary with type of applications, but will normally range from 400 to 2,000mL / 100kg of cementitious material. In most instances, the addition of 600 to 1,600mL / 100kg of cementitious material will be sufficient. Should conditions require using more than recommended addition rates, please consult your local GCP representative.
ADVA Cast 3738 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. ADVA Cast 3738 should not be used together with NSFC-based superplasticiser. Trial mixes need to be carried out to determine the compatibility between ADVA Cast 3738 and other admixtures before use. All admixtures should be separately added to the concrete. Pretesting of the concrete should be performed to optimise dosages and addition sequence of these admixtures.
ADVA Cast 3738 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.
Please contact your local GCP representative for further information regarding the dispensing equipment for this product.

ADVA Cast 3738 accelerates cement hydration at a very early stage. Together with the very efficient dispersion effect, ADVA Cast 3738 achieves very high early strength for the production of precast structural elements.
ADVA Cast 3738 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 3738 produces concrete with superior surface finish, without stickiness, tearing or spotty set characteristics.
With up to 40% water reduction possible, ADVA Cast 3738 is highly effective in low water-cement concrete, producing high strength and high early strength concrete.
The accelerated set times of ADVA Cast 3738 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.
ADVA Cast 3738 is available in 205L drum and in bulk.
ADVA Cast 3738 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 3738 should be maintained at temperatures above 0ºC.
