Polycarboxylate Superplasticizer PRODUCT DESCRIPTION:
Polycarboxylate superplasticizer JF-PL1
Polycarboxylate superplasticizer (PCE) is also called polycarboxylate ether superplasticizer, polycarboxylic ether based superplasticizers, polycarboxylate admixture, polycarboxylate type of superplasticizer. It is the best superplasticizer for concrete at present. We could supply you 3 types of Polycarboxylate superplasticizer (PCE) 50% liquid for different uses.

PCE Application:
1. Polycarboylate mixed with concretes above C45 will result in a more comprehensive and economical effect. Polycarboylate can also be applied in C45 below.
2. The blend dosage range of Polycarboylate is 0.1~0.4% (powder) of the weight of cements or gel material. The regular blend dosage is 0.15~0.30% (powder). Since water reduction rate of concrete mixed with Polycarboylate is relatively high, the concrete slump is sensitive to water content, which shall be strictly controlled during operation.
3. Polycarboylate can be directly added into mixing water or the wet concrete already mixed with mixing water. It is not recommended to add Polycarboylate into dry concrete mixture. Separate batcher and feeding tube are needed.
4. Adaptability of Polycarboylate to most cements are satisfactory, but to some cements, problems such as low water reduction rate, highslump loss may appear. Besides, the fineness and storage time of cement may also influence the application effect of Polycarboylate. In such situation, solutions such as appropriately increase the dosage or formulate other retarding components and so on may be applied.
5. Compatibility problem exists in the formulation of Polycarboylate and other superplasticizers. It is recommended that the necessary formulation experiment shall be conducted before application, so as to obtain the best effect.
6. With the application of Polycarboylate, air content of concrete is increased (usually by 3~5%). It is good for improving the workability and durability of concrete. Certain amount of defoamer may be added if the air content needs to be reduced.
7. Polycarboylate is retarded, and the setting time of concrete can be controlled, so construction requirements can be better satisfied.
Recommended Dosage:
0.4% of the weight of cementitious material in 1m3 of concrete. When applied in ready-mixed station, it should be diluted into solution with the concentration of 10% and the recommended dosage thereafter is 2% of the weight of cementitious materials. For example, 100kg of Polycarboxylate Superplasticizer concrete admixture (50%) (50% concentration) can be mixed with 400kg of water to make solution of 10% concentration.
When Polycarboxylate Superplasticizer concrete admixture (50%) is applied, the dosage normally ranges from 0.3% to 1.2% of the weight of cementitious material in 1m3 of concrete. In order to optimize the dosage, experiments are required before the adoption of it or changing of the cement type.
Packaging & Storage:
This product is liquid, plastic drum, 1 ton / barrel or 200KG / barrel, can also be used for tank storage and storage process anti-seepage and leakage prevention, anti-exposure, anti-high, one year, after the expiration should be tested to determine the use.
