Superplasticising slump retaining admixture

Uses:

• Conplast SP430 SRV is used where a high degree of workability is required and also as an aid to workability retention where delays in transportation or placing are likely or when high ambient temperatures cause rapid slump loss. To facilitate production of high quality concrete of improved durability and water tightness.

Advantages:

• Speeds Construction : Increased workability reduces placing time, equipment and labour element.
• Self Compacting : Conplast SP430SRV modified concrete is highly fluid and needs little or no compaction.
• Reduced Permeability: Better dispersion, reduces porosity and improves water penetration resistance.
• Reduced Segregation: Increased cohesion minimises segregation and bleeding, improving surface finish.
• Longer Placing Time: Conplast SP430SRV gives greater usable life of concrete at high ambient temperatures because of its unique workability retention potential.
• Improved Pumpability: Increased workability and cohesion aids pumping by reducing line friction, dry packing and slump loss due to temperature.
• Chloride Free: Safe in prestressed, reinforced or marine concrete and compatible with sulphate resisting cement or marine aggregate.

Properties

Specific Gravity: 1.260 at 300CChloride content: Nil to IS:456Setting Time: Conplast SP430SRV when used at the recommended dosage level may retard the setting of concrete.Air entrainment: Less than 1.5%

Compatibility: Conplast SP430SRV is generally compatiblewith other Fosroc Admixtures but it is recommended that alladmixtures be added to concrete separately.

Conplast SP430SRV can be used with all types of Portlandcements. For advise on special cements consult local Fosrocoffice.

Compressive Strength: Conplast SP430SRV is primarily ahighly efficient superplasticiser giving large increase inworkability without significant changes in compressivestrength.

Conplast SP430SRV may be used to produce substantialwater reduction resulting in a considerable increase incompressive strength.

Mix Design: As with all admixtures that produce flowingconcrete, the design technique should be based on highcohesion pump mix technology. Specialist advise from Fosrocis available on request.

Application instructions

Dosage: It is recommended that the optimum dosage isdetermined by site trials with the actual concrete mix. As aguide the rate of addition is generally in the range 0.35 to 0.90 litres/100 kg cement for normal mixes & 0.5 to 1 litre/100 kg for high cement content mixes. The higher dosage is used where "flowing concrete" is required and may be found necessary to modify concrete mix proportions. Fosroc can advise on mix design if required.

Curing: Normal curing methods such as water spray, wethessian or a Concure curing membrane should be used.


Storage

Shelf lifeConplast SP430SRV has a minimum shelf life of 12 monthswhen stored in unopened containers below 350C.

Precautions

Health & SafetyConplast SP430 SRV is non toxic. Any splashes should bewashed off with water. If contact with eyes occurs, washimmediately with water and seek medical advice.
FireConplast SP430SRV is non flammable.

High performance water reducing and superplasticising admixture for microsilica concrete
Uses:

• To produce pumpable concrete
• To produce high strength, high grade concrete 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.

Advantages:

• Improved workability - Easier, quicker placing and compaction.
• Increased strength - Provides high early strength for precast concrete if water reduction is taken advantage of.
• 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.

Description

Conplast SP500 is based on Sulphonated NapthalenePolymers and is supplied as a brown liquid instantlydispersible in water.

Conplast SP500 has been specially formulated to give highwater reductions upto 25% without loss of workability or toproduce high quality concrete of reduced permeability.

Properties

Specific gravity 1.250 - 1.270 at 270CpH at 270C Minimum 6Chloride content Nil toIS:456

Compatibility : Can be used with all types of cements excepthigh alumina cement. Conplast SP500 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 flowing concrete thatrequires no compaction. Some minor adjustments may berequired to produce high workable mix without segregation.

Cohesion : Cohesion is improved due to dispersion ofcement particles thus minimising segregation and improvingsurface finish.

Compressive strength : Early strength is increased upto 40% if water reduction is taken advantage of. Generally, there is improvement in strength upto 20% depending upon W/Cratio and other mix parameters.
Durability : Reduction in W/C ratio enables increase in densityand impermeability thus enhancing durability of concrete.

Application instructions

DosageTrials need to be carried out at site to determine the exactdosage of the admixture for the particular mix design andmaterials. However for normal grades of concrete a dosagefrom 0.5% - 1.0% by weight of cementitious material isrecommended, the dosage may be increased to 1.5% toachieve specific slump requirements. For microsilicaconcrete where a high amount of water reduction and slumpretention are required, trials need to be carried out to arrive atthe correct dosage, as the dosage may increase upto 2.0%or even upto 2.5% by weight of cementitious materialdepending on mix design and performance required.

OverdosageAn overdose of above the recommended level of admixturemay result in high workability, slight increase in air entrainmentand retardation of setting time. The ultimate strength of theconcrete will not be adversely affected and will generally behigher than for normal concrete if properly placed and cured. 

DispensingThe measured quantity of Conplast SP500 should be addedalong with the gauging water. For best results, add ConplastSP500 in the last phase after prewetting the mix with 80% ofthe total water required.
