Advantages ÂImproved workability - Easier, quicker placing and compaction.
â¬ Increased strength - Provides high early strength for precast concrete if water reduction is taken advantage of.
â¬ Improved quality - Denser, close textured concrete with reduced porosity and hence more durable.
Â Higher cohesion - Risk of segregation and bleeding minimised; thus aids pumping of concrete
Â Chloride free - Safe in prestressed concrete and with sulphate resisting cements and marine aggregates.
