ADVA® 181
New polymer-based superplasticiser for high strength concrete
Product Description
ADVA® 181 is a high range, retarding, water-reducing, superplasticising admixture based on the latest comb polymer technology. It is specially formulated to produce high strength concrete with good slump retention. It contains no added chloride and is formulated to comply with the following chemical admixture specification for concrete: SS320-1987, ASTM C494, Type G; BS5075 Part 3, 1985.
One litre weighs approximately 1.11kg ± 0.02kg.
Dispersion
Unlike conventional superplasticisers, ADVA 181 is a superior dispersing admixture having a marked capacity to disperse the cement agglomerates normally found in a cement-water suspension. This capability results in lower dosages and better control.
Product Advantages
- Specially formulated for high strength concrete with design strengths above 60MPa.
- Provides a superior combination of long slump life with moderate time extension.
- Highly efficient, producing high slump concrete at very low dosage with no loss in strength, segregation and bleeding.
- Concrete finishes easily without stickiness, tearing or spotty set characteristics.
- It can be added with the concrete mix water for rapid batching.
Applications
ADVA 181 produces concrete with very high strength while maintaining excellent workability characteristics for high slump, pumpable concrete. It also allows concrete to be produced at very low water-cement ratios with no loss in strength.
Dispensing Equipment
Please contact your local GCP representative for further information regarding the dispensing equipment for this product.
Packaging & Storage
ADVA 181 is available in bulk and 205L drums. ADVA 181 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 181 should be maintained at temperatures above 0ºC.
Compatibility with Other Admixtures
In concrete containing ADVA 181 the use of an air-entraining agent (such as DARAVAIR® or DAREX® AEA®) is recommended to provide suitable air void parameters for resistance against freeze-thaw attack. Due to synergistic effects between ADVA 181 and airentraining agents, the quantity of air-entraining admixture added to concrete containing ADVA 181 may be reduced. Please consult your local GCP representative for dosage guidance.
Most water reducers or water-reducing retarders are compatible with ADVA 181 Superplasticiser as long as they are separately added to the concrete. Caution should be exercised when using ADVA 181 together with a retarder, as excessive retardation can occur if the admixture dosages are too high. Pre-testing of the concrete should be performed to optimise dosages and addition sequence of these admixtures. The admixtures should not be in contact with each other before they enter the concrete.
Addition Rates
Addition rates of ADVA 181 can vary with type of application. Typically, dosage rates can range from 200 to 2,000mL / 100kg total cementitious material. However, in most superplasticiser applications, 800 to 1,200mL / 100kg of cementitious material will be sufficient. For best results ADVA 181 should be added to the mix water during the batching process. At a given water-cement ratio, the slump required for placement can be controlled by varying the addition rate. It is GCP’s recommendation that trials are conducted before hand to determine the optimum dosage range to suit your application. If further assistance is required please consult your local GCP representative.
