Product Description
ADVA® 108 is a new superplasticiser based on the polycarboxylate ether polymer technology. ADVA 108 superplasticiser is specially formulated to produce high workability, high slump, flowing concrete with enhanced strength and durability. ADVA 108 contains no added chloride and complies with the following specifications for chemical admixtures for concrete: BS 5075: Part 3; JIS A 6204, EN934-2: 2001. One litre weighs approximately 1.05kg ± 0.02kg.
Dispersion
Based on new comb polymer technology, ADVA 108 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 108 efficiently disperses cement particles using a poweful steric repulsion model. This allows for lower dosages and better control.
Product Advantages
- Long slump life with controlled 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 108 the use of an air-entraining agent (such as DARAVAIR® or DAREX® AEA®) is recommended to provide suitable air void parameters for resistance against freezethaw attack. Due to synergistic effects between ADVA 108 and air-entraining agents, the quantity of air-entraining admixture added to concrete containing ADVA 108 may be reduced. Please consult your GCP representative for dosage guidance.
Most water reducers or water-reducing retarders are compatible with ADVA 108 Superplasticiser as long as they are added separately to the concrete
Caution should be exercised when using ADVA 108 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.
