Product Description
ADVA® 181M is a high performance, new generation mid-range water reducer based on comb polymer technology. It is a ready-to-use liquid admixture with superior dispersing capacity for the cement particles in the concrete mix. This capability exceeds that of normal water-reducing admixtures, resulting in lower dosages and better control.
ADVA 181M contains no added chloride. One litre weighs approximately 1.068kg ± 0.02kg. ADVA 181M complies with the requirements of admixture specifications: SS 320: 1987. BS 5075: Part 3.
Applications
Excellent slump control and slump retention are necessary properties of any high quality concrete. ADVA 181M is a tailor-made admixture that helps concrete achieve excellent slump retention for all ranges of design workability. ADVA 181M is extremely effective in enhancing workability and slump retention even in mid-slump concrete and concrete with manufactured sand (crush granite fines), where conventional admixtures have difficulties achieving these properties.
ADVA 181M is suitable for a wide range of quality concrete, from low to higher grade concrete, by adjusting addition rate. The use of ADVA superplasticiser can help to provide further water reduction when very low water-cement ratio is needed.
Product Advantages
- Provides long slump life with controlled set times.
- Finishes easily without stickiness, tearing or spotty set characteristics.
- Less susceptible to segregation and bleeding.
- Highly efficient, producing desired slump concrete with no loss in strength.
- Quick and easy application to the concrete mix water for rapid batching.
Addition Rates
Addition rates of ADVA 181M can vary with type of application. Depending on the application, dosage rates can range from 600 to 2,000mL / 100kg of cementitious material. For best results, ADVA 181M should be added with the mix water. At a given watercement ratio, the slump required for placement can be controlled by varying the addition rate. Should job site conditions require using more than recommended addition rates, please consult your local GCP representative.
Compatibility with Other Admixtures
Most water reducers or water-reducing retarders are compatible with ADVA 181M as long as they are added separately to the concrete.
Caution should be exercised when using ADVA 181M 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.
ADVA 181M is not compatible with DAREX® Super 20 and DARACEM® products.
