Product Description

DARACEM® 19CFMQ 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. This product has minimal set retardation characteristics.DARACEM 19CFMQ can also be utilized to affect large water reductions thus achieving high performance in both plastic and hardened states.

DARACEM 19CFMQ can also be utilized to affect large water reductions thus achieving high performance in both plastic and hardened states.

DARACEM 19CFMQ is an extremely powerful deflocculating agent and performs by dispersing cement into its primary particles, dramatically increasing flow characteristics of the cement paste.

Main applicational areas are:

  • High quality concrete for durable structures
  • Bridge deck slabs • Silica Fume concrete
  • Pozzolanic and blast furnace slag concretes
  • Reinforced and pre-stressed precast elements
  • Piling & In-situ structures DARACEM 19CFMQ meets the requirements of ASTM C494 Type D and G, BS EN 934-2 and ASTM C1017.

 Advantages

  • High compressive strength concrete especially at early ages.
  • High workability concrete mix with DARACEM 19CFMQ will have the same or higher compressive strength compared to plain concrete of similar w/c ratio.
  • Plastic concrete exhibits high cohesion, fluidity and flowability.
  • Excellent slump retention properties even at high ambient temperatures, whilst exhibiting minimal set retardation.
  • Addition of DARACEM 19CFMQ to plain concrete allows a water reduction of up to 30%.
  •  Low water/cement ratios lead to excellent durability of concrete.
  • Good surface finish, providing highly aesthetic concrete appearance.

Method of Use

DARACEM 19 CFMO 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.

Compatibility with Cements

DARACEM 19 CFMO is compatible with all Portland, Pozzolanic
and Blast furnace cements. It is also compatible with concrete
containing fly ash and or silica fume.

Compatibility with other Admixtures

DARACEM 19 CFMO 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 circumstance

Addition Rates

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.

Effects of Overdosing

Serious overdosing of DARACEM 19CFMQ 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.

Dispensing

It is preferable that liquid admixtures for concrete be introduced into a mixer by means of automatic dispensing equipment, details of which can be supplied upon request.
