Product Description
ADVA® 109 is a new superplasticiser based on the latest polycarboxylate-type polymer technology. ADVA 109 superplasticiser is designed to impart high workability, extended slump life, and increased strength performance and enhanced durability to concrete. ADVA 109 contains no added chloride and complies with BS5075: Part 3. One litre weighs approximately 1.045kg ± 0.02kg.
Dispersion
Based on new comb polymer technology, ADVA 109 is a superior dispersing admixture having a marked capacity to disperse the cement agglomerates normally found in a cement-water suspension. Unlike conventional superplasticisers, which partially rely on electrostatic charge repulsive forces, ADVA 109 efficiently disperses cement particles using a poweful steric repulsion model. This allows for lower dosages and better control.
Product Advantages
- Long slump life with near neutral set times
- Highly workable or low water-cement ratio concrete with little or no retardation
- Finishes easily without stickiness, tearing or spotty set characteristics
- High slump concrete less susceptible to segregation and bleeding
- Highly efficient in producing high slump concrete with no loss in strength
- Easily added with the concrete mix water for rapid batching
Compatibility with Other Admixtures
In concrete containing ADVA 109 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 109 and airentraining agents, the quantity of air-entraining admixture added to concrete containing ADVA 109 may be reduced. Please consult your local GCP representative for dosage guidance.
Most water reducers or water-reducing retarders are compatible with ADVA 109 Superplasticiser as long as they are added separately to the concrete.
Caution should be exercised when using ADVA 109 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 times of these admixtures. The admixtures should not be in contact with each other before they enter the concrete.
