Polycarboxylate Ether Superplasticizer Powder(Concrete additive) - JK-04PP

Description

JK-04PPis a high performance based on polycarboxylate, specifically developed as effective dispersant, fluidized and high range water reducing concrete agent.

JK-04PP 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

• JK-04PP 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.
• 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.

Specification

Advantage

• High water reducing rate and excellent plasticizing effect. And produces concrete with high levels of workability without segregation.
• Excellent dispersion and self-compacting effect can produce different grade strength super fluid self-compacting concrete.
• Can be a substantial increase in early and late strengths of concrete so that increases the project construction schedule.
• Better plasticity-maintaining could significantly prolong the transit time of concrete, which can reduce economic losses and ensure the normal pumping of concrete.
• Improving the frost resistance and carbonation resistance of the concrete. Lower drying shrinkage of the concrete by 20% or more compared with naphthalene-based admixtures.
• High applicability: It can be used with different variety of cement.
• Improving finished concrete surface ability.
• Proffering air environment protect.

Dosage

0.18– 0.22% by weight of cement. 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.
