Compatibility with other Admixtures
DARASET 580C is compatible with air-entraining admixtures such as the DAREX® AE Series; water reducers such as WRDA® P4 and WRDA P7; mid-range water reducers such as WRDA 90, and high-range water reducers such as DARACEM® 205. DARASET 580C should not be premixed under any circumstances with other admixtures. While some admixtures can be usefully combined within the same mix, the performance of this product may well be affected by the presence of other chemicals. We recommend that GCP Applied Technologies be contacted for advice in all such circumstances.
Addition Rates
Range: 500 ml – 4000 ml per 100 kg cement (0.5%-4.0% volume by weight of cement)
The amount of DARASET 580C used will depend on specific job conditions, on local materials and on the degree of set acceleration and early strength development required. Typical addition levels range from 500 ml to 2000 ml/100 kg cement, but levels as high as 4000 ml/100 kg cement can be used.
DARASET 580C is supplied ready for use. Since DARASET 580C may be used at high dosages, the concrete producer should account for the water contained in the DARASET 580C. One litre of DARASET 580C weighs approximately 1.40 kg.

One litre of DARASET 580C weighs approximately 1.40 kg and added to a concrete mixture will contribute 0.77 kg of water to that mixture.
Overdosing of DARASET 580C will produce an increased rate of setting and a reduction of the ultimate concrete strength.
