Conplast SP500

Conplast SP500 is a high performance water reducing and superplasticising admixture for microsilica concrete.
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.

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.

• 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 determine the exact dosage of the admixture for the particular mix design and materials.
However for normal grades of concrete a dosage from 0.5% – 1.0% by weight of cement is recommended, the dosage may be increased to 1.5% to achieve specific slump requirements. For microsilica concrete where a high amount of water reduction and slump retention are required, trials need to be carried out to arrive at the correct dosage, as the dosage may increase upto 2.0% or even upto 2.5% by weight of cement depending on mix design and performance required.

Conplast SP500 is supplied in 200 litre drums.
