Polycarboxylate Superplasticizer PRODUCT DESCRIPTION:
 
Polycarboxylate superplasticizer JF-PL1
 
Concrete retarder is a kind of concrete setting agent, which delays the initial and final setting time of concrete without affecting the later strength of concrete. It can be used alone or combined with water reducing agent, which has a certain water reducing effect.
 
TYPICAL PROPERTIES:

 
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.
 
Product characteristics:
1. This product consists of various kinds of compounds, such as phosphate, tartrate, gluconate and so on.
2. It has good retarding effect on concrete and mortar.
3. It has good compatibility with polycarboxylate superplasticizer.
4. Wide adaptability.
5. Non-poisonous, non-odor, and non-corrosivity.
 
Precautions:
1. This product is non-toxic and harmless, biodegradable, but not edible.
2. If it gets into the eyes, it should be rinsed with plenty of water in time.
3. If you cause allergies to part of the human body, you should consult a doctor in time.
 

 
Precautions:
 
1. JF series polycarboxylic acid water reducer mother liquor is non-toxic, harmless and non-corrosive, but it is prohibited to eat. If it is accidentally in the eyes or in the mouth, rinse immediately with clean water;
2. When used with other admixtures, compatibility test should be conducted.
