Conplast SP430
Conplast SP430 is based on Sulphonated Napthalene Polymers and supplied as a brown liquid instantly dispersible in water. Conplast SP430 has been specially formulated to give high water reductions upto 25% without loss of workability or to produce high quality concrete of reduced permeability.
USES
- To produce pumpable concrete
- To produce high workability concrete requiring little or no vibration during placing.
- To produce high strength, high grade concrete M30 & above by substantial reduction in water resulting in low permeability and high early strength.
Advantages
- Improved workability - Easier, quicker placing and compaction.
- Improved quality - Denser, close textured concrete with reduced porosity and hence more durable.
- Increased strength - Provides high early strength for precast concrete with the advantage of higher water reduction ability.
- 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.
