AQUAJAVA
(New-Generation-Concrete Superplasticiser)
Description: AQUAJAVA
is high range water reducing concrete admixture based
ob polycarboxylate, the new generation concrete Superplasticiser.
AQUAJAVA can reduce unit water upto 35% and has extraordinary
capacity to retain workability for about 2 to 3 hours.
The slump (workability) loss depends not only on temperature,
but also on the type of cement, the nature of the aggregates
and the method of transport. It is strongly recommended
that the concrete should be properly cured in hot and
dry climate.
Mechanism
of Cement Dispersior: AQUAJAVA type of polymers
at low dosage dispense the cement gains in a concrete
mix due to their preferential absorption and strong
hydrophilic character of ALKOXY Polyglycol chains together
with steric repulsion of the carboxyl groups. Unlike
Poly Melamine and Poly Naphthalene Sulphonate in which
only electrical repulsion is responsible in fluidifying
hydrating cement paste, Polycarboxylate imparts dual
action of steric hindrance and hydrophilicity.
Advantages:
AQUAJAVA
considerably improves the properties of fresh and hardened
concrete improves Sulphate resistance and has low chloride
ion penetration.
- Improves
pumpability especially with low cement contents and
lack of fines making workability more independent
of the granding of the aggregates.
- Improves
Rheological properties making the concrete self compacting
(SCC).
- Makes
concrete fair faced and smooth with low porosity.
- Achieves
a higher slump than ordinary Superplasticiser at low
water cement ration.
- Long
workability and extremely good slump retention.
- High
ultimate strength
- Lower
dosages compared to conventional superplasticisers.
- High
compression and flexural strength at all ages.
Uses:
High
performance and durable concrete for Hydel & Thermal Power
Plant where Maximum water - cement ration is 0.35
- In
situ piling concrete.
- Reinforced
concrete spum Pipes.
- Under
- water concreting.
- Hot
water (summer) concrete.
- Concrete
in Marine Environment & sewage treatment plant.
- Structural
concrete having high durability.
- Concrete
Pavement, Roadways & Precast Tiles.
- Precast
Blocks for flyover & Bridge.
- Micro
silica concrete.
- Slip
Forming.
- Ready
- mix concrete business - High Haulage Time.
Compatibility:
AQUAJAVA
is compatible with ordinary Portland, slag and Fly-ash
blended cement.

Mixing:
AQUAJAVA is ready - to - use liquid, which is dispensed
into the concrete together with the mixing water. The
plasticizing effect is higher if these admixtures are
added to the damp concrete after 50 - 70% of the mixing
water is added. The addition of AQUAJAVA to dry aggregate
is not desirable.

Normal concrete 0.4 - 1.5% on cement weight
(Water / Cement ratio Higher than 0.35)
