Description
Polycarboxylate Superplasticizer PCE Liquid for Slump Retention Type(50% Solid Content) is polycarboxylate ether based high performance copolymer designed for highest concrete quality. It enables concrete to be produced highly workable at low dosage with improved slump retention. It has very good slump retention and adaptability to different cement and materials, especially for summer high temperature construction conditions and long-distance concrete transport project.
Polycarboxylate Superplasticizer Liquid for Slump Retention Type (50% Solid Content) is a neutral concentrate grade, it is mainly used as a raw material together with Water Reduction Type to produce different types of high performance water reducers for targeted industrial. It complies with ASTM C 494, Type F specifications.
Uses
Polycarboxylate Superplasticizer Liquid for Slump Retention Type(50% Solid Content) can keep good performance in high temperature for a long time, especially for construction in high temperature in summer. It can be used for long time transportation, poor slump retention caused by high temperature, and other construction requirements and construction areas. 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.
Advantages
▼ Improve slump retention time in concrete.
▼ Effect long distance transportation for a long period of time.
▼ Reduce slump loss and improve workability.
▼ Decrease bleeding of materials separation.
▼ 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 increase the project construction schedule.
▼ Better plasticity-maintaining could significantly prolong the transit time of concrete, it reduce economic losses and ensure the normal pumping of concrete.
▼ 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.
▼ High applicability: It can be used with different variety of cement.
▼ Improved finished concrete surface ability. Proffer air environment protect. No chloride ions and no corrosion to steel bar.

Dosage
0.2 to 0.8% by weight of cement (usually dilute 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.
Package, Storage & Shelf Life
It is packed in 1.1ton IBC tank and Flexitank.
Keep container closed when it is not in use, store in dry, cool and shaded place.
Shelf Life: Minimum 12 months when unopened. After the expiration date, it can be used if testing results is qualified.
