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.
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.

Aquaproof Anchoring Systems is authorised project Super stockist and brushbond authorised Fosroc applicator for Fosroc Chemicals(India) in Pune, Maharashtra and a leading dealer for construction chemicals.

• 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.

Trials need to be carried out at site to optimise the dosage of the admixture for the particular mix design and materials. However as a guide the rate of addition is generally in the range of 0.5% to 1.2% by weight of cement for normal grades of concrete. A dosage of upto 1.5% may be used depending on the mix design and to achieve specific slump requirements.

Conplast SP440 is supplied in 200 litre drums.
