DARACEM 150F
Concrete Superplasticiser
Product Description
DARACEM ®150F is a high performance liquid superplasticiser that has been developed to enhance and
improve the slump retaining properties of concrete, whilst providing improved ultimate compressive
strengths. It is an extremely versatile and flexible product and is effective over a wide range of cement
contents and cement types.
DARACEM 150F is especially beneficial in high durability concrete mix designs. It can be used effectively in
cementitious systems that utilise Ground Granulated Blast Furnace Slag, Pulverised Fuel Ash, Silica Fume or
Portland Cements.
DARACEM 150F is particularly useful for imparting extreme workability to concrete mixes so that large or
difficult pours can be made, especially under hot climatic conditions.
DARACEM 150F is formulated from carefully selected raw materials and is manufactured under controlled
conditions to give a consistent product. It is an extremely powerful deflocculating agent and performs by
dispersion of the cement into primary particles, dramatically improving flow of the cement paste.
DARACEM 150F meets the requirements of ASTM C494 Type D and G, BS EN 934-2 and ASTM C1017.
Advantages
DARACEM 150F is especially suitable for producing high workability concrete that has excellent
workability retention. In this application, minimum extensions of setting time and little loss in early age
compressive strength are observed.
High workability flowing concrete can be obtained by incorporating DARACEM 150F into a concrete mix
designed for a 50 mm slump. Normal pump mixes are recommended for this application.
DARACEM 150F can be used to effect high range water reductions, typically up to 30%, leading to
considerable increases in compressive strength. Impermeability and durability are correspondingly
improved.

Method of Use
DARACEM 150F is supplied ready for use.
When producing high workability concrete it should be added in its supplied form to the batching water,
prior to the addition of the cementitious component. After the addition of cement, further mixing is
recommended to enable DARACEM 150F toefficiently disperse the mix components
Compatibility with Cements
DARACEM 150F can be used with all types of cements, including Limestone Cements. It is also effective in
concretes containing pulverised fuel ash or ground granulated blast furnace slag. For use with special
cements we recommend that you consult GCP Applied Technologies.
Compatibility with other Admixtures
DARACEM 150F 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 be contacted for advice in all
such circumstances.
Addition Rates
Range: 500 ml–3000 ml per 100 kg cement(0.5%–3.0% [v/w] by weight of cement)
As with most products of this type, the magnitude of the effect obtained with DARACEM®150F is
governed by the quantity of product used and the specific nature of the concrete and its constituent
materials.
It is therefore necessary to assess performance under site conditions using site materials to determine
optimum dosage and effect on both plastic and hardened concrete properties, such as cohesiveness,
workability retention, set characteristics, early rate of strength gain, ultimate compressive strength and
shrinkage when these are of consequence. As a guide to these trials, and addition level of 1.2%–1.4%
DARACEM 150F volume/weight of cement is recommended.
Addition rates outside the recommended dosage range may be used for special concrete applications. This
may be the situation when Silica Fume or Blast Furnace Slag Cement is used. 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.
For advice and assistance with
Effects of Overdosing
The effects of overdosing DARACEM 150F are a function of the degree of overdose
When producing high workability concrete, overdosing will increase the level of workability and may induce
the onset of segregation.

Product Data Sheets
Depending on the extent of the overdose, an increase in the setting time may also occur, especially in low
temperatures and/or when employing sulphate resisting cement or cement replacement materials.
In any situation where overdosing is suspected, a careful inspection of the concrete in its plastic state
should be conducted. Particular attention should be paid to consistency and cohesiveness, prior to a
decision on the suitability of the concrete for the particular application in question.
Dispensing
It is preferable that liquid admixtures for concrete should be introduced into the mixer by means of
automatic dispensing equipment. Such equipment is available from GCP and details will be supplied on
request.
Health and Safety
DARACEM 150F is formulated from chemicals which present no fire or health hazards.
For further information see DARACEM 150F SDS (Safety Data Sheet) or consult GCP.
Packaging
DARACEM 150F is supplied in 210 litres, non-returnable containers.
Alternatively, 1000 litre IBCs or bulk deliveries can be arranged.
Storage
DARACEM 150F should be stored in original containers or suitable closed tanks, preferably out of direct
sunlight and protected from extremes of temperature.
Storage Life in Manufacturer’s Drums:
12 months from the date of manufacture.
Storage Life in Bulk Storage:
12 months from the date of manufacture
