DARACEM® 19-CFMQ is a high performance liquid concrete superplasticiser that has been developed to impart extreme workability to concrete mixes so that large or difficult pours can be made, whilst maintaining excellent slump retention properties, especially under hot climatical conditions. The product has minimal set retardation characteristics.
DARACEM 19-CFMQ can also be utilized to effect large water reductions thus achieving high performance in both plastic and hardened states.
DARACEM 19C-FMQ is an extremely powerful deflocculating agent and performs by dispersing cement into its primary particles, dramatically increasing flow characteristics of the cement paste.

DARACEM 19-CFMQ is supplied ready for use, and should be added to concrete mixes either during the mixing cycle or at the same time as the water, or alternatively it should be added in its supplied form to a normal concrete mix a few minutes before the pour is made.
In the latter case a mixing cycle of at least 2 minutes should be provided to ensure complete dispersion.
DARACEM 19-CFMQ is compatible with all Portland, Pozzolanic and Blast furnace cements.
It is also compatible with concrete containing fly ash and or silica fume.
DARACEM 19-CFMQ 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 and we recommend that GCP Applied Technologies be contacted for advice in all such circumstances.
Range: 0.60%–2.0% volume by weight of cement The optimum dosage is assessed after preliminary trials depending upon the actual mix constituents and specifications required. Addition rates outside of the recommended dosage range may be used for special concrete applications. In such circumstances it is important to conduct preliminary trials on the actual mix constituents to assess the effect on the properties of the concrete at the dosage level specified.
Serious overdosing of DARACEM® 19-CFMQ will generally produce a concrete mix of even greater workability. Set retardation and a slight increase in air entrainment may be noticed. In SRC mixes and cooler weather, set retardation will be further increased. If intentional or accidental increases above the recommended addition rates are encountered, care must be taken to allow for the effect on the stripping time of formwork. In such cases, however, provided the concrete is properly cured, the ultimate strength will generally be higher than for normal concrete.
It is preferable that liquid admixtures for concrete should be introduced into a mixer by means of automatic dispensing equipment, details of which can be supplied upon request.
For further information see the DARACEM 19-CFMQ SDS (Safety Data Sheet) or consult GCP.
DARACEM 19-CFMQ is supplied in 210 litre, non-returnable containers. Alternatively, 1000 litre IBCs and bulk deliveries can be arranged.
DARACEM 19-CFMQ should be stored in original containers or suitable closed tanks, preferably out of direct sunlight and protected from extremes of temperature.
