Improved Workability – Easier, quicker placing and compaction. Increased Strength – Provides high early strength for precast concrete if water reduction. Improved quality – Denser, close textured concrete with reduced porosity and hence more durable. Higher Cohesion – Risk of segregation and bleeding minimized; thus aids pumping of concrete. Chloride Free – Safe in pre stressed concrete and with sulphate resisting cements and marine aggregates. Provides sharp / fine edges in carving works without damage.
