High Performance Superplasticising mixture
To produce pumpable concrete
To produce high strength, high grade concrete M30 & above
by substantial reduction in water resulting in low permeability
and high early strength.
To produce high workability concrete requiring little or no
vibration during placing.
Improved workability - Easier, quicker placing and
Increased strength - Provides high early strength for precast
concrete with the advantage of higher water reduction ability.
Improved quality - Denser, close textured concrete with
reduced porosity and hence more durable.
Higher cohesion - Risk of segregation and bleeding
minimised; thus aids pumping of concrete
Chloride free - Safe in prestressed concrete and with sulphate
resisting cements and marine aggregates.
Conplast SP430 G8 complies with IS:9103:1999 and BS:5075
Part 3 .Conplast SP430 G8 conforms to ASTM-C-494 Type ‘G’
and Type ‘A’ depending on the dosages used.
Conplast SP430 G8 is based on Sulphonated Napthalene
Polymers and supplied as a brown liquid instantly dispersible
Conplast SP430 G8 has been specially formulated to give
high water reductions upto 25% without loss of workability or
to produce high quality concrete of reduced permeability.
Specifi c gravity 1.24 to 1.26 *
Chloride content Nil to IS:456 *
Air entrainment Approx. 1% additional air
* The uniformity parameters like specifi c gravity, pH, chloride
content etc. will vary for specifi c customer requirements and
mix design. Please refer our MTC issued for specifi c product
confi guration for measuring our product parameters that will
be constantly and consistently administered.
Compatibility : Can be used with all types of cements except
high alumina cement. Conplast SP430 G8 is compatible with
other types of Fosroc admixtures when added separately to the
mix. Site trials should be carried out to optimise dosages.
Workability : Can be used to produce fl owing concrete that
requires no compaction. Some minor adjustments may be
required to produce high workable mix without segregation.
Cohesion : Cohesion is improved due to dispersion of cement
particles thus minimising segregation and improving surface
Compressive strength : Early strength is increased upto 20%
if water reduction is taken advantage of. Generally, there is
improvement in strength upto 20% depending upon W/C ratio
and other mix parameters.
Durability : Reduction in W/C ratio enables increase in density
and impermeability thus enhancing durability of concrete.
The optimum dosage is best determined by site trials with the
concrete mix which enables the effects of workability, strength
gain or cement reduction to be measured. Site trials with Con-
plast SP430 G8 should always be compared with mix containing
no admixture. As a guide, the rate of addition is generally in
the range of 0.5 - 2.0 litres /100 kg cement.
