JK-04PL-WR Polycarboxylate Superplasticizer
High Water Reduction Type(Liquid, Solid Content 50%)
High Range Water Reducing Concrete Admixture
ASTM C494, Type F
De
JK-04PL-WR is a high performance based on Polycarboxylate ether, specifically developed as effective dispersant, fluidized and high range water reducing concrete agent.
JK-04PL-WR is a neutral concentrate grade, it is mainly used as a raw material to produce different types of high performance water reducers for targeted industrial. It complies with ASTM C 494, Type F specifications.
Uses
Ø JK-04PL-WR can be applied in a wide variety industry and can improve the workability to the concrete and to improve high early compressive strength, even with low water/cement ratios while maintaining normal levels of workability.
Ø It can be widely used in conventional concrete, pumping concrete, super-fluid self-compacting and high-performance concrete; it has the excellent performance especially in the application of high-strength high performance concrete.
Advantage
Ø Low dosage and high water reducing rate can reach 30%-40%, excellent plasticizing effect. And produces concrete with high levels of workability without segregation.
Ø Excellent dispersion and self-compacting effect can produce different grade strength super fluid self-compacting concrete.
Ø Can be a substantial increase in early and late strengths of concrete, so that increase the project construction schedule.
Ø Better plasticity-maintaining could significantly prolong the transit time of concrete, it reduce economic losses and ensure the normal pumping of concrete.
Ø Improves the frost resistance and carbonation resistance of the concrete. Lower drying shrinkage of the concrete by 20% or more compared with naphthalene-based admixtures.
Ø High applicability: It can be used with different variety of cement.
Ø Improved finished concrete surface ability.
Ø Proffer air environment protect.
Ø No chloride ions and no corrosion to steel bar.
Dosage
0.25– 0.5% by weight of cement(usually dilute to liquid of 20% solid content). Standard water reduction at normal dosage and significant water reduction at higher dosage. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.

Cautions
Ø Mud content of sand and stone and quality variety of admixtures has great effect on water reduction, so standard aggregate and admixtures are recommended.
Ø Cannot be added together with rosin soup air entrainer.
Ø Cannot be kept in
Ø When mixing and measuring the slump loss, be aware that it takes longer time to be in effect than naphthalene admixtures.
Ø Do not mix with naphthalene-based admixtures. If other admixtures, such as set retarder or corrosion-inhibiting admixture, are required simultaneously for some special projects, compatibility tests should be conducted beforehand.
