Superplasticiser EB821-R Retarding
Superplasticiser For Concrete Conforms to BS 5075
Part 3 & ASTM C494 Type A & G
is a retarding superplasticiser containing sodium
salt of high molecular weight sulphonic polymer. It
is specially formulated for production of high
quality, high early and ultimate strength
water-tight concrete that possesses excellent
may reduce the required
mixing water by 15 to 20%
while maintaining the required workability and hence
expedites early strength development and improves
ultimate strength of the concrete.
production of high strength concrete
the water: cement ratio.
excellent slump retention.
substantially the concrete workability at given
water:cements ratio sand therefore aids flow and
compaction around reinforcements.
production of self-compacting concrete which
eases placing in difficult situations and
alleviates the need for vibration.
the production of fair-faced concrete.
pumping of concrete and therefore reduces the
pumping pressure required.
reduction in cement content used for given
shrinkage and crazing cracks in mass concrete.
