Conplast SP439 is based on modifi ed Polymers and supplied as a brown liquid instantly dispersible in water. Conplast SP439 has been specially formulated to give high water reductions without loss of workability or to produce high quality concrete of reduced permeability
Improved workability - Easier, quicker placing and compaction. Increased strength - Provides high early strength for precast concrete with the advantage of higher water reduction ability. 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.
