Jk-04PP

Uses

• JK-04 PP can be applied in a wide variety industry and canimprove the workability to the concrete and to improve high earlycompressive strength, even with low water/cement ratios whilemaintaining normal levels of workability.
• It can be widely used in conventional concrete, pumpingconcrete, super-fluid self-compacting and high-performanceconcrete; it has the excellent performance especially in theapplication of high-strength high performance concrete.

Advantage

• High water reducing rate and excellent plasticizing effect. Andproduces concrete with high levels of workability withoutsegregation.
• Excellent dispersion and self-compacting effect can producedifferent grade strength super fluid self-compacting concrete.
• Can be a substantial increase in early and late strengths ofconcrete, so that increase the project construction schedule.
• Better plasticity-maintaining could significantly prolong thetransit time of concrete, it reduce economic losses and ensure thenormal pumping of concrete.
• Improves the frost resistance and carbonation resistance of theconcrete. Lower drying shrinkage of the concrete by 20% or morecompared with naphthalene-based admixtures.
• High applicability: It can be used with different variety ofcement.
• Improved finished concrete surface ability.
• Proffer air environment protect.
• No chloride ions and no corrosion to steel bar.

Dosage

0.18– 0.22% by weight of cement. Standard water reduction atnormal 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 ambienttemperature. Therefore, in many cases it is advisable to carry outtrial mixes.

Cautions

• Cannot be added together with rosin soup air entrainer.
• Cannot be kept in metal container for too long.
• When mixing and measuring the slump loss, be aware that ittakes longer time to be in effect than naphthalene admixtures.
• Do not mix with naphthalene-based admixtures. If otheradmixtures, such as set retarder or corrosion-inhibiting admixture,are required simultaneously for some special projects,compatibility tests should be conducted beforehand.
