Fosroc Conplast SP 440

Product Description

Conplast SP440 is a blend of organic polymers and is supplied

as a brown liquid instantly dispersible in water.

Conplast SP440 has been specially formulated to give high

water reductions upto 25% without loss of workability or to

produce high quality concrete of reduced permeability.

Properties

Specifi c Gravity : 1.17 to 1.19*

pH at 270C : Minimum 6*

Chloride content : Nil as per IS:456 and BS:5075*

Air entrainment : Approx. 1% additional air is

 entrained

* 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

configuration 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 SP440 is compatible withother types of Fosroc admixtures when added separately tothe mix. Site trials should be carried out to optimise dosages.Workability : Can be used to produce fl owing concrete thatrequires no compaction. Some minor adjustments may berequired to produce high workable mix without segregation.Cohesion : Cohesion is improved due to dispersion of cement particles thus minimising segregation and improvingsurface fi nish.Compressive strength : Early strength is increased upto 40%if water reduction is taken advantage of. Generally, there isimprovement in strength upto 20% depending upon W/C ratioand other mix parameters.Durability : Reduction in W/C ratio enables increase in densityand impermeability thus enhancing durability of concrete.
