• Increases strength of concrete • High early and 28 days strength if advantage of water reduction is taken. • Retains the initial workability for longer time. • Cost effective. • Can be used with higher grade of concrete. • Safe in prestressed concrete. • Improves cohesion thus aids pumping of concrete. • Makes the concrete denser, hence durability increases. • High water reduction is possible. • Chloride free. • Ideal for mass concreting, pavement concrete.
